For decades, the standard advice was to spay or neuter a cat at about six months. Many owners still wait for that date, and some are surprised by a litter first.
The recommendation has changed. Veterinary organizations now advise doing it earlier, by five months.
Key figures

What changed
A veterinary task force on feline sterilization launched the Feline Fix by Five initiative, which calls for spaying or neutering cats before five months of age. AAHA reports that the concept has been endorsed by the AVMA, AAHA, the feline veterinary association, the Association of Shelter Veterinarians and a long list of other groups.
Why earlier is better
- Prevents surprise litters. Many kittens reach puberty before six months.
- Easier surgery. Procedures in younger cats are generally quicker.
- Faster recovery from anesthesia and surgery.
- Fewer minor complications, according to the veterinary literature AAHA cites.
- Less spraying and roaming when males are neutered before those habits start.
Cost and where to go
The ASPCA’s cost estimates put a cat’s spay or neuter at around $150, though prices vary widely. Many shelters adopt out cats already sterilized, and low-cost spay and neuter clinics exist in many areas. The ASPCA keeps a directory.
If an adult cat is not yet spayed or neutered, it is still worth doing. Ask your vet about timing, especially for a female who may be in heat.
The first-year cat cost guide places setup and veterinary spending together. The carrier guide covers transport equipment for the appointment.
Questions people ask
What is the best age to spay a cat?
Veterinary groups now recommend before five months of age, under the Feline Fix by Five initiative.
Can a kitten get pregnant before six months?
Yes. Many female kittens reach puberty before six months, which is one reason for the earlier recommendation.
Is early spay or neuter safe?
According to the literature AAHA cites, surgery before five months has no more major complications and fewer minor ones than at six months or older.
Will neutering stop my cat from spraying?
Neutering before the habit starts greatly reduces spraying. Once established, it may continue and need other steps.
