Source code would be cool. With some tweeking you could edit the source for other animals. Is there any other stats formula out there that does this kind of thing?

Differential equations are great for modeling these sorts of problems. http://www.geom.uiuc.edu/education/calc-init/population/

Completely inaccurate, at least for where I live. If it were true, the world would be a much less sad place. But reality cares not for cute kittens.

Here in the northeast US, feral cats (or even indoor cats with a comfy life) will never have two litters in a year. You are guaranteed one per year though. Maybe in Florida things are different.

Most kittens will never survive. We "had" one very feral cat. She would not even touch food we left out, until she was 20 years old and had cataracts in both eyes. Her secret to a long life? Dump all the kittens. Don't even let them nurse if you can help it. She had a dozen litters over the years. Most all died within two months, the lucky few lasted six. We buried all the ones we could find. Only one kitten of all her litters made it past a year.

The half life of a feral kitten is around three months. With a typical litter of five (including the runt who will get abandoned at a few weeks), maybe one will make it past a year. If no one starts feeding the extra cat, it won't even make it that long.

Edit: One final note. The life span and litter size of cats is very close to that of squirrels. True, squirrels have less environmental impact, being herbivores. (But this just means an environment could support an even larger number of squirrels.) The world is not drowning in squirrels (except for maybe Cornell) despite no one ever fixing the squirrels on their property.

If the entire cat population after five years originated from one female I think the total would be somewhat less than that estimated due to negative genetic effects - mainly inbreeding depression: http://en.wikipedia.org/wiki/Inbreeding_depression.

Earlier quoted context omitted.

Realistically, sure, but if someone were really determined to carry this out in real life - let's say, the government of Thailand for no real reason - they'd be able to afford to feed 10,000 cats pretty easily. Oh, and what if we assume that the cats can or will eat each other, or corpses of other cats?

Feeding 10,000 cats--not that hard. Getting 10,000 cats to breed optimally--pretty much impossible. Heck, try getting three of them to optimally not fight each other for a week at a time.
