My cat is about a year old now and her brother got to her if you know what i mean. I think she may be pregnant but I can't tell. What are the signs and will the kittens be affected seeing as they are siblings? Thank you for your time.
Both animals should have been spayed and neutered! The gestation period is 63 days. During that time her belly will swell. There is an incresed chance of congenital and/or hereditary problems. vetcare
