Hello.... I think my cat is pregnant but I want to make sure if she is or not, without going to the vet to see if she is. She's doing what my other cat has done whenever she was pregnant; she's eating anything she can get to and she's bigger on her belly. One night she got out and that day she was in heat, I think, because she was in heat the day before.... but when she came back, she seemed like she was in heat but didn't stay like that for as long as she usually did. And if she is, she is not a normal size cat, she is extremely short, so would that effect anything on her? Please help.
