A mother cat can be spayed when her kittens are eating canned food regularly, which is typically when they are between 5-6 weeks old. A mother can be returned to her kittens to nurse them 24-30 hours after spay surgery.
Both male and female kittens can be spayed as early as 10-12 weeks of age, although this varies somewhat from vet to vet. Cats usually reach sexual maturity around six months â¦old and some even younger at four months, so it is best to spay kittens before that age.
