⚡ In short
- Most vets recommend 4–6 months, before the first heat.
- It greatly reduces mammary tumour and uterine infection risk in females, and spraying and fighting in males.
- Recovery usually takes 10–14 days (5–7 for males); a cone and stitch check matter.
- Energy needs drop after neutering — adjust food or your cat will gain weight.
Best age
Female cats usually have their first heat at 5–6 months, sometimes earlier, so most vets recommend surgery at 4–6 months. Shelters safely neuter kittens from 8–16 weeks; your vet decides based on weight and health. Adult and older cats can also be neutered after a health check; older cats may need blood tests first.
Benefits
- Females: spaying before the first heat greatly lowers mammary tumour risk and removes the risk of pyometra and ovarian/uterine cancer; no more loud heat behaviour.
- Males: urine spraying usually decreases or stops; less roaming and fighting, and lower risk of diseases spread by fights such as FIV.
- Prevents unwanted litters.
Recovery and aftercare
- Drowsiness and low appetite on day one are normal; offer a small meal when your vet says.
- Stop licking the wound with a cone or surgical suit.
- No jumping, running or baths for 10–14 days.
- Check the incision daily; slight pinkness is normal. Go to the stitch check (often day 7–10).
Feeding after neutering
Energy needs drop by roughly 20–30% while appetite often rises. Weigh food, ask your vet about neutered-cat diets, weigh your cat every 2–4 weeks and play 2–3 times a day.
Frequently asked questions
At what age should a cat be spayed?
Most vets recommend 4–6 months, before the first heat. Your vet sets the exact timing.
Will my cat gain weight after neutering?
Energy needs drop, so without adjusting food it will. Weighing food and daily play prevent weight gain.
How long is recovery?
Males usually recover in 5–7 days, females in 10–14 days.
