I have 2 lovely cats just a year old who are sisters, been convinced peppa is pregnant due to over affection, weight gain and pink nipples. A week later her nipples are now pale and she's quite obviously in heat, crying out. Due to my door being repaired she managed to get out and was with a Tom. This was a few days ago now and she's still very much in heat. This is my first experience owning cats so I have no idea if it is possible to be in heat and pregnant. Also her sister Zoe is regularly attacking her, I can only assume the constant cries are cracking her up just as much as it is me, I've tried to separate them but find it unfair as they have both always had the run of the house. Any advice anyone can give me will be great. P.S both cats will be spayed as soon as I can, most likely this month providing Peppa isn't pregnant
