How do I know my small kitten's age and when to get him fixed?

Updated On September 23rd, 2025

How can you tell how old a male kitten is ? Im not sure how old he is, hes a kitten but i cant tell how old he is. Im not sure if he was the runt of the litter or if hes only a couple months old. He does still try to suck on my one male cat (but my 7yr old cat does this to blankets). Hes still small but i need to know if hes getting to the age of needing to be fixed. Hes also very hyper. Ive attached 2 different pictures of his teeth and one of him sleeping.

Most cats can be fixed once they are over a certain weight rather than a certain age. Bringing him to your vet to be weighed and talking with your vet can let you know if he is large enough to be neutered. Your vet can also check for any remaining baby teeth in his mouth, as well as adult teeth that have come in to give you a closer estimate of his age. (It's hard to tell from your photo if those are still baby teeth or if they are adult teeth coming in, but this usually happens starting around 3-4 months of age, and finishes around 6-7 months.)
