Could she be pregnant? Her nipples are pointy but otherwise look normal. I'm just concerned because she looks so HUGE and I think this is why she hasn't been adopted yet. Or, she could have gained a lot of weight just by sitting in her cage all day for weeks on end.
When I pick her up to put her back in her cage, I'm careful of her belly and she doesn't protest. My cat is a little fatty but not to this extent and she's definitely not firm in the lower region. That's what worries me the most.
Pics ahead. Just fat, or possibly pregnant?
