Savannah Weights

[SV Dad]

Hey John,
How about this for an idea? Scatter plot of generations vs weights. Code the generations with different colors. Wonder if we get a bell shaped curve with enough data?

I need a ton more data to have anything significant. About the only standout thing thus far, are later generations don't have as much deviation. I'm sure with enough samples that any generation would be bell shaped just beginning to wonder if I can get there.

What a great thread hope you get enough data John .... ours are too young for your survey but at 8 months old there is a noticeable difference in Male vs female just for interest ... Rough weights ( taken with me holding them on the bathroom scales so not accurate )
Loki f6 sbt 10 lbs neutered male
Freyja f6 sbt 6lbs spayed female

That's interesting to see so early in the data collection. Methinks you are onto something.

Ziggy F2, 7mo, neutered male 19.5#

Ziggy is one big boy at 7 months! Looks like he will be joining Razi in the big outlier club.

I don't think it's much different than what we've heard here, outside weight being more predictable in later generations. It's definitely a bit of a challenge as a big cat like Razi at 31lbs (average of his weight range) isn't erroneous data, he's just like Michael Jordan or Wayne Gretzky as far as Savannah weight goes. Clearly bigger than the general population, just need enough data to actually prove it. With a small data set, Razi definitely throws things off and while it's ok to remove data that doesn't represent the general population, first you really need to have enough data to prove that a savannah of his weight represents less than 1% of the population.

I don't plan on excluding any data, as I don't think it's good science. If that data point becomes a source of problem for the rest of the data, I'll note it's exclusion. A long way off from there at the moment although if you were just to look at what the media has to say about SVs, a cat like Razi would be the norm.

Would it help to get more data? I can probably do that from some of the other lists...

Most definitely! More data is always better. So far the majority of data I have is from earlier generations and predominately male Savannahs. The data definitely has a trend line that can be followed, just some samples of some smaller and larger cats that leave some holes. I'd love to have 75-100 samples or more then I wouldn't have any issue putting the data up to be scrutinized. At that point it's also something solid enough to put in front of a state legislature or really contend with one of the under informed articles written.

Thanks Paige!

No worries, John! Let me see what I can do.

Oh and Jacq, sorry for singling out Razi, he's just obviously a pretty special boy.
