Will My Cat Get Fat?

It’s a good idea to reduce the food portions you give your cat after the surgery, as some cats tend to gain weight after the surgery is performed. This is because after the surgery, due to hormonal changes, your cat will need around 25% fewer calories than it did before. You can always give your cat food that is specifically made for neutered or spayed cats for the best results.

Do You Need to Neuter an Indoor Cat?

Yes, you should still have your indoor cat neutered. You never know what will happen, and your cat could easily slip out. Not only does it stop female cats from going into season, but it also cuts down on certain diseases in both female and male cats. In reality, it’s just better for your cat’s health and your home environment to have the cat fixed.

Will Neutering Stop a Cat from Spraying?

While it’s not guaranteed, neutering often stops a male cat from spraying or marking his territory. It is possible that the cat will still spray if it’s upset or anxious about something. However, if your cat stopped spraying and then started again, talk to your vet to determine the cause of the problem.


Cats can eat before being spayed and neutered, but there are limitations to how much they can eat and at what age. You can give them water up until the surgery time. However, if you’re worried about how much you can feed your cat, it’s best to ask your vet when you go in to make the appointment.

While you can have cats neutered or spayed at 4 months of age, your vet will let you know when it’s time, and some cats are still too small to undergo surgery at that age.
