I have inherited my daughter's two cats (her new husband is allergic). One cat is normal size...the other one weighs almost 18 pounds and looks like a raccoon.

Both are fed the same amount, both go up and down the stairs together, and in fact, the fat cat is very quick on her feet and is always running outside when I open the door.

I can't figure out why she is so much fatter. She is healthy and agile, but she is just plain FAT!

Well, I had a cat that weighed 16 pounds, though his weight fluctuated between 13 and 16. He was not a small cat, so was just big, not really fat. I'm sure like people there are animals that are very thin, and others that are much huskier. It still does not explain these 30- 40 pound tubbies, unless than have the same type of glandular problems that some very obese humans suffer with.

I have a horse like that. He stays fat on much less feed than the others get. He also has a prehensile lip and can open gates and latches unless they are chained. His determination is enormous.

Sounds like me!!!
