Overview
If your cat is pregnant, one of the first things you’ll notice is a change in her nipples. This can start as early as three weeks after mating, and it’s often one of the clearest signs that kittens are on the way.
Cat pregnancy typically lasts about 63 to 65 days, and each stage comes with its own changes. Recognising early signs, like the nipples becoming more visible or a shift in your cat’s behaviour, can help you support her through a healthy pregnancy.
