Key Takeaways
Spaying and Neutering
Spaying and neutering are surgical procedures that remove a cat's reproductive organs, preventing them from producing offspring. Spaying refers to the removal of the ovaries (and usually the uterus) in female cats; neutering refers to the removal of the testicles in males. Both procedures are performed under general anesthesia by a licensed veterinarian.
The standard feline spay is an ovariohysterectomy (removal of both ovaries and uterus), though some veterinarians perform an ovariectomy (ovaries only). Neutering in males is technically called orchiectomy.
What Actually Happens During the Surgery
Both spay and neuter procedures are performed under general anesthesia, meaning your cat is completely unconscious and feels no pain during the operation. A veterinary team monitors heart rate, breathing, and temperature throughout.
For a spay (female cats), the surgeon makes a small incision in the abdomen and removes the ovaries and, in most cases, the uterus. The incision is closed with sutures, some of which dissolve on their own. The entire procedure typically takes under an hour.
For a neuter (male cats), the surgery is simpler and faster. One or two small incisions are made in the scrotum, the testicles are removed, and the incisions may be left to close naturally or sealed with sutures. Most male cats are discharged the same day.
Before the procedure, your vet will ask you to withhold food for several hours to reduce the risk of complications with anesthesia. A pre-surgical check confirms your cat is healthy enough for the operation.
Ask Your Vet About Pre-Surgical Bloodwork
Many veterinarians recommend basic bloodwork before anesthesia, especially for kittens with unknown health histories. This screens for conditions that could increase anesthetic risk. It's a simple step that adds an extra layer of safety to an already routine procedure.
Why Timing Matters
The age at which your cat is spayed or neutered has real health implications. Traditionally, the four-to-six-month window has been recommended because it comes just before most cats reach sexual maturity — and before the behavioral and health risks that come with it.
For females, spaying before the first heat cycle dramatically reduces the lifetime risk of mammary (breast) cancer. Spaying also eliminates pyometra — a serious, sometimes fatal infection of the uterus that can develop in intact females, particularly as they age.
For males, neutering early reduces the likelihood of roaming, inter-cat aggression, and urine spraying inside the home. It also eliminates the risk of testicular cancer entirely.
Some owners wonder whether waiting until a cat is older has benefits. Current veterinary guidance for cats generally supports early neutering, unlike some recommendations for certain dog breeds where later timing may be advised. See our article on spay/neuter decisions in dogs for a comparison of how recommendations differ across species.
~90%
Reduction in mammary cancer risk with early spay
Veterinary research suggests spaying before the first heat cycle reduces mammary tumor risk by approximately 91%, according to widely cited veterinary oncology data.
4–6 months
Recommended spay/neuter age for cats
The American Association of Feline Practitioners and many veterinary organizations support neutering cats at or around four to six months of age.
10–14 days
Typical full recovery window
Most cats return to normal activity within two weeks, with males often recovering faster given the less invasive nature of the neuter procedure.
What to Expect During Recovery
Most cats recover well with basic home care and a little patience. Here's what a typical recovery looks like:
- Day 1–2: Your cat may be groggy from anesthesia, less interested in food, and quieter than usual. This is normal.
- Days 3–7: Energy often returns quickly, especially in males. This is when it's most important to restrict jumping and rough play to protect the incision.
- Days 7–14: The incision continues to heal. If sutures need removal, your vet will schedule a follow-up appointment.
Check the incision site daily for redness, swelling, or discharge. An Elizabethan collar (the cone-shaped plastic collar) prevents your cat from licking or biting at the wound. Keep the area dry — no baths during recovery.
If you notice excessive swelling, an open incision, or your cat stops eating for more than 24 hours post-surgery, contact your veterinarian promptly.

Scheduling Around Vaccinations
Spay and neuter surgery is often coordinated with your cat's vaccination schedule. Your vet may prefer your kitten to have completed certain core vaccines before surgery. See our cat vaccination schedule guide for a breakdown of timing and what each vaccine covers.
