Cat castration

What happens during the operation

Castration (neutering) a cat involves the complete removal of the testicles. The location of the incision is over the scrotum. The main reason why this procedure is carried out is to prevent unwanted behaviours such as roaming and aggression and spraying (marking) in the house.

Castration is carried out under a full general anaesthetic. Due to the anaesthetic, your pet may be sleepy and a bit unsteady for the next 12-24 hours. During this time, your pet should be allowed to rest quietly in a warm (not too hot), comfortable, draught-free place and should be monitored closely.

Prior to the anaesthetic your pet will have an Intravenous catheter placed allowing vascular access, this is so we can inject the anaesthetic agent directly into the vein. Some hair will be shaved on their leg so we can visualise the vein and clean the skin. Once your pet is ready to go home we will remove the catheter and place a bandage which will apply pressure to the vein to stop bleeding and help reduce any bruising. If this bandage is still present when you take your pet home please unwrap the bandage and place into the bin.

During the operation, the veterinary surgeon will make a very small incision to remove the testicles, this incision is so small that it does not require to be sutured (stitched) afterwards.

Wound care

Licking can slow down wound healing and introduce infection. We have supplied you with a buster collar. This should be worn at all times although can be removed for feeding; please ensure he is supervised to ensure he does not lick or chew the wound.

Please monitor the wound for any pain, swelling or discharge. Please do not cover the wound.


Please keep your cat indoors for the first 3-5 days.


Although your pet has been offered a small meal while in the hospital they can be offered another light meal tonight. This should be easily digestible such as cooked chicken and boiled rice or white fish. Alternatively, you can purchase a tin of Royal Canin Gastrointestinal food from reception. 

Normal appetite should return in 24-48 hours so can be offered their normal diet the day after surgery. 

Once fully recovered reduce your pet’s daily amount of food by approximately 1/4. Their metabolism will start to slow down and reducing food intake will help prevent obesity.

If your pet has not eaten within 48 hours of her operation, he is listless, unsteady, painful or you have any other concerns about the wound or her well-being please telephone us for advice on 01383 722818.

We operate an out of hours’ service after 7pm and if you’re very worried about your pet and feel that they can’t wait until the next day for an appointment, please call 01383 722818 to arrange an emergency appointment.
