I noticed toward the end of december that she had bumps UNDER her teets like they were developing. The vet said she may be pregnant or she may soon have her first heat cycle. OK, well now her teets are a lot pinker and bigger, she has no milk but the blood vessels on her tummy are palpable. It freaked me out at first because I thought she had a worm under her skin but I have read that the mammary gland vessels enlarge. SHe doesnt seem fat and pregnant until you look at her standing up, her tummy is slightly rounded but still not very big. I never saw her go into heat or do the tango with my old tom, he is gone now. I think she is pregnant. SHe is 7 mths old this month
