Before Surgery

Our vets will perform a thorough clinical exam on your pet to ensure that they are in good health and fit for surgery. A medical history will also be taken.

As each pet iCastrating Your Male Cats different we may decide to run a pre-anaesthetic blood test, which gives us a clear indication of your pet’s overall health. We advise that your cat is fasted from 8 pm the night before the operation to prevent reflux of the stomach contents entering the lungs (pulmonary aspiration of the stomach content).

About the Operation

When to Castrate your Cat

What are the Risks?

With any type of surgical procedure, there is some risk involved. Our vet will carry out a health check the morning of the procedure to ensure your dog is healthy. Constant monitoring by our nurse during and after the surgery ensures these risks are as low as possible.

Going Home

After surgery, your cat’s appetite may be reduced and he may also appear quieter than usual; this is normal and he should be back to normal the following day. Even though there are no sutures to be removed we will still carry out a post-operative check after 3 days to make sure the wound is healing nicely. He will need to have his stitches taken out 10-14 days after the surgery. However, if you are in any way worried about your cat don’t hesitate to contact us.
