Any savannah outdoor cats?

As has been discussed at length in other threads, the kitten I talked about in my previous posts passed away when he was only 8 months old. His illness was most probably the dry version of FIP, and whatever it was, it was something internal gone awry and there is no reason to think it had anything to do with him being allowed out..

Moggie was really special and I was devastated. Below is a link to a short video showing some of my favourite clips of him including some of the best parts of his free roaming life. To make sure this is in context, it seemed best to share this here, in this thread...The first picture was taken after one of his early door dashes.

https://drive.google.com/file/d/1rSu6NE-K59tQGgd619Tk8jKjvE9UCF3d/view?usp=sharing

I have been living with a new F7 SBT kitten (referred to here as HB) for the past few months and having learned some things about SVs from living with Moggie, there is some things I have decided to do differently.

I have had extensive conversations with 2 local vets about the risks of allowing a cat to be free roaming in this area, and both assured me the risks in my area are minimal and normally easily managed, and they both have free roaming cats themselves.

I personally think the idea that all cats should be indoor only, even in low risk areas, and the refusal to believe low risk places exist, is too extreme.... of course low risk is not no risk, but we allow our kids to ride bicycles and swim and do other unnecessary things that have some risks, because it improves the quality of their lives and the risks are small. I don’t see any good reason why cats should be different.

But like the OP I have had concerns there might be things in an SV personality that might put them more at risk than normal. The person I got HB from did not contradict the local vets, but sensibly pointed out that if I want what is best for him, it is best he never get a taste of a freedom if it may be a problem to allow him to continue. This makes sense to me, even in a situation that seems low risk, and is something I can completely agree with.

To make sure it was me making these decisions, I built a second door on an entry way to the back door and there has never been a door dash that ended in getting outside. And I have been really careful to always take my kitten out the door in a cat back pack. Which has been working really well. If he wants to go out he gets in the pack and meows. If I put the pack out of sight, he just accepts there is no way out. There is a cat flap leading to porches on all 3 sides of my house that are enclosed in heavy duty wire mesh and I need to open all the doors from latches installed on the inside so no surprise vistors can let the cat out. And the more civilized ground level area under the house is also part of the enclosure.

I think it is important for a cat to get to go outside, both for their mental development and to learn about the territory surrounding their home. Even with precautions it seems there is a substanial risk they will accidentally get out, and cats that have never gotten familiar with the lay of the land, and the dangers it contains and how to get home, are IMO much more vulnerable to getting lost and having panicked accidents. Which seems to be the main way tragedy happens when people have Savannah cats outdoors. So I think as long as it doesn’t lead to them trying to get out, (and that is a big if) taking a cat out for daily walks around their home is like vaccinating them in case they ever get out by accident.

Taking the new guy out on a leash has convinced me he is probably never going to be suitable to be an unsupervised outdoor cat.

Moggie had some kind of free roaming Dad and maybe he inherited some survival strategies from him which seem to have been mostly bred out of my more purebred cat. Moggie seemed to have a inborn caution and the first couple months being outside, the main thing he did was practice running back to the house from various points in the yard. From there he seemed to very slowly expand his territory cautiously getting familiar with it, but as far as I saw he was firmly attached to home and never ventured further than the next door neighbours yards. With HB a lot of his instinctive caution and a strategy to slowly establish a territory seems missing and he seems to have much more of a tendency to just go... Maybe this tendancy to have a looser attachment to home turf is what makes SVs more like a dog on a leash ? Anyways... I have the impression that initially, if I was not on the other end of the leash he would have ended up a couple miles away before it occurred to him he should have been making notes on how to get home. He is getting more sensible with expereince, but I really don’t want him roaming and he does seem he would be inclined.

Moggie’s ears always noticed everything and you could see him evaluating stuff even if his attention was focused else where. As other people mentioned here, SVs have a peculiar narrow focus, and I have noticed this too. When HB is absorbed in something else he often doesn’t seem to notice the sounds of cars or passerbys until the last minute.

Another problem is when something spooks him, whether it is a car or an passerby, his initial lack of caution quickly changes into full on panic and bolt mode, and he doesn’t seem to be making sensible decisions. It is easy to imagine him roaming to the other side of the road, and when the one car every 1/2 hour drives by, deciding to bolt in the direction of home at the last minute. Which would be really dangerous. Or if he was in the woods getting spooked and climbing a 100 foot tree where he might never be found.

Another part of my considerations is that HB seems much more compliant, domesticated and content being indoors or on a harness than Moggie was. Moggie had a serious “You are not the boss of me” attitude going... HB just occasionally flirts with this. I have been attaching his retractable leash and him in a secure walking jacket to a 100’ long heavy duty overhead wire I installed in the deer fenced garden while I work beside him hands free. Moggie totally panicked when I tried this, but HB loves hanging out down there, trying to catch bugs in the mulch and watching birds. And with a bit of practice, being on a harness doesn’t seem to bother him at all. I started getting him used to this by standing still in one spot and holding the leash for a few minutes every time we went for a walk. The slippery overhead wire and 15 foot retractable leash give him 3000 square feet to roam.

The main thing I learned from Moggie is that super playful streak SVs are known for can easily become a passion for hunting. Moggie’s caution and strong attachment to me seemed to keep him nearby, but HB is a lot more independent and if given his freedom, it is easy to imagine him ending up a couple miles away, living on rabbits for days or even weeks at a time. That is not an acceptable possibility for me...

So as long as I can keep him reasonably happy, even though IMO he won’t have the same quality of life Moggie enjoyed, and that does bother me, I much prefer always knowing where he is.

Sorry this is so long... making a decision as to what is best has been hard with a lot of factors to weigh.

And while I am on a roll…

I think the information in this link that differentiates between the outcomes for pet cats that are cared for and have outdoor access, and feral cats, is probably accurate. According to this, pets with outdoor access live on average 2 to 3 years less than indoor only cats. As the average indoor cat lives to be 15, that would be like a human living on average to 75 years indoor only, or on average to 60 indoor/ outdoor.

https://www.vetinfo.com/indoor-outdoor-cat-life-expectancy.html

But what is average could be better or a lot worse depending on the environment and personality of the pet....

The biggest issue with outdoor cats is the attrition rate in the first year is sky high. So while the overall life expectancy may be 2 to 3 less years, it does not clearly depict the risks of the first year. Our male Himy never strayed from my husband's side and could be trusted outside, unlike his mother and sister. My SV girl is so scatterbrained when chasing after things that there is no way that I would ever let her loose for a second.

I should also state that the potential shortening of the lifespan by any amount is simply unacceptable to me. Our cats go out with a walking jacket and have an enclosure for outdoor enrichment.

I was curious and tried to find a study showing that pet kittens that are allowed outside (but not including feral kittens) have a 50% mortality rate in the first year, and instead I have fallen down a statistical rabbit hole where I seem to have found evidence purebred Persian kittens would be more likely to survive their first year in a feral cat colony as long as they were spayed or neutered ...Which has got to be wrong...

This study linked to below, of feral cats in Tennessee, shows that feral kittens that are not neutered or spayed have a 75% percent attrition rate during the first 6 months, and the next 6 months the attrition rate is only a bit higher than for fully mature cats. Another study found if the feral kittens were spayed and neutered the attrition rate dropped to 24% in the first 6 months. Which I take to mean these studies suggest that neutered and spayed feral kittens have a better than 50% survival rate the first year. It is hard to see how a spayed or neutered pet kitten that is allowed outside but has the benefit of human protection, food, shelter and health care would have a higher attrition rate than a spayed or neutered feral kitten.

“In reference to neonatal and juvenile individuals, Nutter et al. (2004) reported that out of a population of 169 cats, 81 had died or disappeared within 100 days (or 3.33 months) of birth.”

“46/169 cats died or disappeared between 100 days and 6 months. “

“Since our model considers adult cats to be those individuals greater than seven months old, we adjusted the monthly adult survival rate given by Danner et al. (2010) by rounding up to account for a slightly decreased average monthly survival rate for adults when the smaller monthly survival rates for months eight through eleven were incorporated”

“Despite the difference in values used to construct the model, a 75% death rate within the first year of life is reasonable in comparison with other studies (Nutter et al., 2004; Warner, 1985).”

“Gunther & Terkel, 2011). Gunther et al. (2011) found that in a population of unaltered cats, the survival rate for the first six months was 32%, a value similar to that found by Izawa and Ono (1986). The survival rate in a population of altered individuals was 76% (death rate 24%). “

More detailed information on some of these studies on feral cats mortality is here - and it mentions that the outcome varies depending on the environment. Dogs killing the feral kittens were a big factor..
https://www.researchgate.net/public...oaming_domestic_cats_and_kitten_survival_rate

But then I found this study that says purebred kittens born in catteries supposedly have an average 34% mortality rate in the first year...

https://www.researchgate.net/public..._kitten_syndrome_and_neonatal_isoerythrolysis

“In a large survey of purebred catteries, the overall kitten mortality rate from birth to 1 year of age averaged 34.5%.(29)”

If this is correct there isn’t as much difference between the survival rates of completely feral kittens and indoor only purebred kittens as it first appears, and it sounds like neutered feral kittens might even have a better first year survival rate than purebred kittens who would be mostly indoor only... And I really doubt that is true!

I didn't find any studies with stats for regular pet kittens that are allowed outside...

With all the wild animals around our place I wouldn't dare let the boys out even in an enclosure. When a cougar is bold enough to rush at a human (me, yes it was scary), it's definitely not safe enough for the cats.

You have to look at the source of studies... Done are scientific and some are not. I don't but the Persian kitten study at all.

Rereading Rafiki’s post I realized it didn’t say anything about the attrition rate in the first year being 50%... Sorry for being addled and confusing what you said with what I read elsewhere. Not sure how I did that...

I did find a study by the Royal Veterinary College in the UK. It does not differentiate between indoor only and outdoor cats, but shows that in a population where more than 90% of the cats are allowed outside about 6% of kittens die in their first year, with trauma being the cause of about 1/2 of these deaths followed by viral infections. It looks like close to 17% of cats in the UK die before they are 5 years old, and 5.5% in the first year, with close to 1/2 of these deaths caused by trauma, and 60% of the traumas being caused by roads and traffic. Purebred cats live on average 1.5 years less than cross breeds. But overall, in a population where 90% of the cats are allowed outdoors, the average lifespan of a neutered or spayed cat with vet care in the UK is 15 years.

“over 90% of UK cats have daily outdoor access”
“Overall, the median longevity was 14.0 years”
“Neutered cats (15.0 years


Below is the same study with a graphic.

http://skeptvet.com/Blog/2015/03/longevity-causes-of-death-in-pet-cats/

One thing that jumps out at me is it looks like even though 90% of cats in the UK are allowed outside, it appears they live just as long on average as indoor only cats in the US. On the other hand, it looks like on average 8.8 percent of pet cats in the UK die of trauma in their first 5 years, and a 10% attrition rate in the first 5 years is more than I would be comfortable with...

But these are averages and a cat living in a rural area away from main roads where only 1% of its home turf is roads, is much less likely to be hit by a car than a cat living where 25% of the accessible areas are roads.

Not meaning to argue, as I actually agree HBs chances might be as bad as 50/50 if I just opened the door... and I have no plans to do this....but if we all really believed no percentage of risk was acceptable and we all gave no weight to the quality of a cats life in eliminating all possible risks, we would keep our cats in padded rooms and crates all the time. I think most people who love their cats weigh the potential and likely risks their specific area, against their cats individual needs and quality of life, and try to make as informed decision as possible.. but every descion carrys some risks.

And I think it is often overlooked that just keeping a cat in that wants out, is a risk in itself as if they get desperate they can do dangerous things to get out. Many indoor only cats do get out accidentally, and if they have never been given a chance to get familiar with their territory they are less likely to find their way home.

https://lostpetresearch.com/2016/12/cat-homing-behavior-survey-results/

Again, not meaning to argue. I just wish someone would do more detailed research on the subject and look at variables like the breed of a cat, the age a cat was first allowed out, the process used to introduce them to the yard and surrounding area, the type and quantity of roads in the area, the predators, whether the kitten was raised by a Mom who could teach it about the local dangers, how many indoor only and outdoor access cats go missing and are never found, ect.

Most indoor/outdoor Savannahs go missing and are never found...I don't need a study to prove that to me... It's evident by all the missing and lost Savannahs. Europe is completely differed than the US for some reason, although most owners there do not allow their Savannahs out either. They may have fun outside, but their life will be shorter... That is the risk you take.

There is nothing wrong with having an outside enclosure or taking them for walks... Then they have the best of both worlds.

Why? The reasonable person test here is that there are myriad things we know can cause harm to free roaming pets, that some animals are better survivors than others, and that none of us can control all the variables that lead to good/bad outcomes. Choosing to allow a cat to be indoor-outdoor or outdoor only is a calculated risk.

Your rationalizations and over-analysis of this subject has become trite.

Agreed, I find that some people read the risks to letting their cats out and from that moment do all they can to keep their cat safe, while others try to rationalize why this isn't necessary or why it is so much better to allow them to risk their lives. I often suspect it is because to keep a cat indoors requires more effort... either in enriching the home, adding a safe outdoor enclosure or cat-proof fencing or spending more time interacting with the cat so that they are content in their home. Easier to open the door and let them roam, but to make it more palatable they justify it for other reasons.
