I took in a unwanted cat in early December. The earliest a vet could schedule her to be neautered was beginning of February. She was in heat I tried to keep her in but one day I had to call an ambulance for my son and the door was left open for the paramedics so she did get out while in heat that was on the 17th December and she didn't come back until the 18th. There was / is 2 male cats in the area that was lurking and calling for her while she was in heat too so I'm pretty certain she more than likely mated with one if not both male cats. I was reading up on possible cat pregnancy signs (today would be day 21 / 22 after the possible mating) and noticed one about cat nipples being more pink / red but honestly I'm not sure what a non pregnant cat nipples are supposed to look like so I've taken a picture in hope someone could help if they look different to 'normal' If she is pregnant what do I do? thank you for any help.
