Kittens should be spayed or neutered when they reach sexual maturity, which is usually between four and six months of age. However a cat can be safely spayed or neutered at any age, so even older adopted cats should have this procedure.
The kittens were divided into three groups: 1  Group 1 (11 kittens) were neutered or spayed at 7 weeks of age. 2  Group 2 (11 kittens) were neutered or spayed at 7 months. 3  Group 3 (the control group of 9 kittens) were not neutered until maturity and after the completion of the first phase of the study at 12 months.
