Cats reach reproductive maturity rapidly; we follow the RSPCA and Cats Protection guidelines recommending neutering both female and male cats around four months of age. Spaying a female cat involves removing their ovaries and uterus. Castrating a male cat involves removing both of their testes.

What is meant by spaying?

Spaying is the common term used to describe the surgical procedure known as an ovariohysterectomy. In this procedure, the ovaries and uterus are removed completely in order to sterilize a female pet. Sometimes an ovariectomy is performed where only the ovaries are removed.

What is neutering?

Neutering (also known as castration) is the common term used to describe the surgical procedure during which both testicles are removed in order to sterilize (make infertile) a male pet, therefore stopping his ability to reproduce.


Neutering your cat Neutering or spaying your cat:

  • Prevents unwanted pregnancies and womb infections

  • Can help prevent tumours and breast cancer

  • Can also help prevent testicular cancer and prostate disease

  • Assists in preventing roaming and aggressive behaviour
    It’s normal to neuter! 86% of owned cats in the UK are neutered*

Should I let my cat have one litter before spaying her?

This happens to be a common question, and there are no known health benefits to letting your cat have a litter; this is also the same for dogs and rabbits.

General anaesthesia

Your pet requires a general anaesthetic for neutering; here at Animal Ark, we have measures in place to ensure their safety during the procedure. A dedicated Registered Veterinary Nurse (RVN) will monitor your pet throughout their surgery and recovery. All anaesthesia comes with some form of risk; however, these are very low, especially neutering, as pets are often young, fit, and healthy when having this procedure.

Risk levels of anaesthesia increase with a pet’s age, certain breeds and if your pet has any underlying health conditions. We can perform a pre-anaesthetic blood test before your pet’s surgery to detect any underlying illnesses; this can be discussed when booking in for the procedure and on the day of their surgery. Your pet will receive a premedication to relax them and will also receive two types of pain relief.  Rest assured the Animal Ark team will be with your pet every step of the way.

Your pet will stay the day with us

On admission, we will discuss the procedure and go through the consent form. Please note we must gain a signature from the registered owner (over 18) or authorised agent on the consent form. Your dog, cat or rabbit will be admitted as a ‘day patient’, and they will be discharged later that day once our team are happy with how your pet has recovered. During your pet’s discharge appointment, the team will go through everything you need to know about caring for your pet after their surgery and their pain relief medication. We are always at the end of the telephone for you and your pet, so please contact us if you have any further questions once you have your pet settled back at home via 020 8599 8544

Please bring your cat in a secure cat basket with a blanket that smells of home. Cats are territorial creatures who prefer to stay in areas familiar to them; click here to read how you can prepare for travelling to us with your cat. 

Highly advised but optional:

  1. Pre-anaesthtic blood test: This bloodwork allows your veterinarian to assess your pet’s overall health, ensuring that your pet is a good candidate for anesthesia. If preanesthetic bloodwork shows any abnormalities, these abnormalities can be addressed by making any necessary adjustments to your pet’s treatment plan thereby reducing the risk of an anaesthesia
  2. Intraoperative iv fluids: maintains your pet's blood pressure and decrease the risks of organ damage from decreased blood pressure, prevent dehydration and to aid in recovery.

Patients will require either a buster collar or medical suit at an additional charge to prevent your pet from licking or opening their surgical incision and reduce the risk of post-operative complications

Please also be aware that we are dedicated to providing the best care for your pet during their stay with us: Our nursing teams are overseen by our nurse supervisors who are certificate holders in Emergency & Critical Care. Difficult anaesthesias are overseen by our Clinical Director who has completed specialised training in Anaesthesia at a referral hospital in the US.
