Ok so a few weeks ago it was very cold out side and someone drop off a beautiful calico cat so we brought it in our house. Once we got it in it looked very hungry so we fed it and made it a little bed in our house. The cat is awesome and it has been a few weeks and her belly started getting big. At first we didn't really no but now we are wondering if it is pregnant. Its belly is big but nipples are very little. We heard their bellys would get big if they had worms but I looked and didn't see any. I have a few pictures I will post if needed. Thanks for any help and I forgot to say this cat is young but as you no I do not no ifs it the first litter of kittens because it wasn't our cat. Thanks again for any help.
