Usually a cats first season is somewhere between 4 and 10 months old with average age around six months. Siamese and Burmese cats are quite precocious and will often have their first season at 4 months of age.
Fertility Facts. There is no set-in-stone breeding season for cats, and a female can have up to 5 litters in one year, with each litter producing anywhere from 3 to 6--or more!--kittens. Though their fertility may decline as they age, cats have no equivalent of menopause and can become pregnant even in their advanced years.
