Cali is now 36 days pregnant and the other day I noticed that she looked really skinny and was afraid that she miscarried the babies somewhere and I didn't notice. so as I was looking under the bed (she was following me around) and I happened to look over at her from a side angle and noticed that all her baby weight from the sides is now on the bottom. she is carrying really low. Is this normal for this stage in her pregnancy? the other thing that is worrying me is she is acting like, to put it in polite terms, a female dog. she has always been the sweetest cat, now whenever anyone gets near her while shes in this mood she growls and hisses, she also sits in the corner and twitches her tail back and forth, (you know the angry twitch) the only one she really allows around her is Guardian. when my dog gets near her she always freaks out and claws his nose. she has always been on friendly terms with him, now she acts like hes going to eat her! this happens about three times a day then the rest of the day she is back to her lovable self. but the most worrying thing is that she has taken to biting, she was always a nibbler when you would pet her she would gently bite your finger but now she bites hard enough to draw blood!it seems like she is frustrated with something but I don't know what!!!! Is she trying to tell me something, or is this just hormonal?
