Alexis,

The teats are usually the first sign. They get big and pink. Depending on how far along a cat is, the belly will bulge a little. As far as her appetite is concerned, it could be she might have a case orf worms. Ask your vet to give her a dose or two of Drontyl. They can usually be seen in her poops. There are other types of parasites that would also cause her appetite to increase.

As far as being pregnant and aborting kittens, let me explain it a little better.

When a cat is pregnant and goes into be spayed, it's not like a human abortion. The vet takes out the whole uterus, kittens and all. The kittens never meow, breath or move. I am pro-choice and would rather have THAT than bring in unwanted kittens into an already over crowded world. But that is only MY opinion.

I highly doubt your cat is pregnant. The best way to find out is to have the vet check her out. Bring a stool sample (no more than 24 hours old).

Good luck and keep us posted.
