F1s are extremely energetic and very smart. When they get bored, they make their own brand of fun and it can get messy.
I have 4 SVS -- 2 F2s, an F6 and an F1. The F1 is the only who does not scratch furniture. He has turned on the faucets and flooded the laundry room and kitchen. The boy loves to play in water. He is large -- 22 inches at the shoulder and 39 inches long. And he is strong. So when he launches himself of the leather couch after a toy, he leaves marks and sometimes holes and snags fabric furniture.
One of my F2s is more destructive than the F1. The F2 is the reason all my breakables are stuck down with QuakeHold as well as the art on the walls. The F2s and F6 decided my dining room chairs were preferred scratching posts rather than the ones I bought for them so the chairs are covered in thick towels.
That said, I've had to do the following to the house since getting the F1:
* change all interior knobs to knobs that lock from both sides -- to keep him out of rooms he shouldn't be in and to keep in a room when I need a break from his antics;
* change plastic hoses on washer to steel because he bit through the plastic ones, causing flood #2;
* change all the wood floors to vinyl plank because of his love of water (and also because my husband is better suited to living in a barn than in a human's house
);
* replaced window treatments -- he did shred the custom stuff we got before we decided to get an F1;
* installed child-proof locks on all cabinets/drawers/toilets;
* installed keyed locks on 2 custom furniture pieces where we keep books and important papers.
There's more that I can't think of at the moment. I did a rough tally about a month ago and, including the floors which were not necessary to change, we've spent around $30,000 changing things in the house to accommodate the F1. That doesn't mean you'd have to do the same. My boy is one of those cats who must be kept busy when he's awake or all hell can break loose.
The important things to remember about getting an F1 are:
The cat needs you and you must be able to spend sufficient time playing with it no matter how tired/sick you are. If you work outside the home that means play before you leave, when you come home, and before bed for at least an hour each time. If you work at home, plan on not getting much done.
F1s tend to bond to one person so the cat may love you and tolerate others in the family or vice versa. The cat may not like when you have visitors and may need to be locked up during those times.
If you plan on taking vacations, you should raise the cat with whoever will be the cat sitter. I had the sitter come twice a day to play with him and feed him after he'd been home for 2 weeks. He's known her since he was a baby and he still gets pissy with her when we're gone for longer than a week. He's knocked her down twice. The reality is, you may not find anyone who wants to watch the cat and vacations could become challenging to take.
I have to put Atticus in the cat enclosure when the housekeepers come because one is terrified of him. He is not mean but he hissed at her once and that was all it took. Same with friends -- he tolerates them for a bit and then he wants them gone.
And most important -- they are eerily similar to 3 yr old children with the same inquisitive nature and need to be involved in EVERYTHING you do. Spend a day at a pre-school in a room full of kids who are high on sugar, need a nap and refuse to take one and you'll get a sense of living with an F1 is like. Then multiply that by a gazillion.
