Can cats still think they're pregnant even though they aren't?

Question

I have two cats, a boy and a girl. They are both brother and sister. The female became in heat and ended up getting pregnant by her brother so we had them both spayed and neutered so the babies had to be taken out of her, prematurely because we were afraid of the issues the kittens may have, so we ended it. But it has been I'd say a year and the female cats eats nonstop and always throws it up. Is she over-eating to try and feed her non-existing babies? Does she think she is still pregnant?

Answer 1

I Guss so mine dose she lays around all the time and act,s like she in heat that is weird for them to do that but that happens. With some cats.

Answer 2

If she was spayed that long ago, it probably is not a hormone issue. It might be something behavioral, or something in the food she is sensitive to. It makes sense that if she throws up, she'll be hungry sooner and eat again and repeat the cycle.

Throwing up that often for any reason is not good for a cat's digestive system. Call the vet!
