I've never been a cat person, but last year a kitten by the name of lucky walked into my now fiance's life, and we ended up with 2 more after her to add to our collection. All 3 are fixed, up to date on shots, and healthy. But as my fiance was playing with our girl lucky, he noticed a "fat" pouch under her belly area. I squished it around, and it causes her no pain. Is this normal? And is it just that... fat? A lady I work with said her cat has it too... is it dangerous? or bad for their health? She's not huge, a little pudgy (since getting fixed), but she looks like a kangaroo!
