Question: at what age is a cat no longer a kitten?
Answer: The kitten will have a full set of adult teeth by about 7 months old. At 5-6 months the kitten is old enough to be spayed or neutered. Kittens can start to look like adult cats by 6 months of age thus they need nutritional support for optimum health and development during their growth phase which lasts 12 months.
