Neutering — or castration — is the surgical removal of the testicles. It is one of the most commonly performed veterinary procedures and, for most healthy males, involves a straightforward recovery of just a few days.
Neutering eliminates the risk of testicular cancer entirely. It also significantly reduces the risk of prostate disease, including benign prostatic hyperplasia (BPH), a condition where the prostate gradually enlarges under the influence of testosterone and can cause difficulty urinating and defecating. BPH affects the majority of intact male dogs by middle age.
In cats, neutering dramatically reduces the risk of certain infectious diseases. Intact male cats roam, fight, and bite — behaviours that directly drive the spread of Feline Immunodeficiency Virus (FIV), a serious and lifelong disease with no cure. Neutering curbs these behaviours and helps protect your cat and others in the community.
Additional benefits of neutering include:
- Significant reduction in roaming behaviour — and the injuries, accidents, and lost pets that come with it
- Reduced inter-male aggression and fighting
- Elimination of urine marking and spraying in cats — a particularly strong motivator for many owners
- Reduced mounting and hormone-driven behaviours
- Elimination of the urge to escape in search of a mate
The ideal age for neutering depends on your pet's species, breed, and size. For cats, neutering is generally recommended around 6-8 months of age. For dogs — especially medium to large breeds — we may recommend waiting until closer to physical and hormonal maturity, as emerging research suggests that s*x hormones play a role in musculoskeletal development. This is a conversation worth having with us, as the right timing is individual to your pet.
Neutering reduces hormonally driven behaviours — it does not alter your pet's fundamental character, playfulness, or affection toward you.
While neutered pets can have a slightly lower metabolic rate, appropriate diet and exercise are all that is needed to keep your pet at a healthy weight.
Every year, thousands of animals enter shelters across Canada because of unplanned litters. Neutering your male pet means he cannot contribute to that number — and that matters.
If you have questions about neutering your dog or cat — the timing, what to expect, or anything else — we are always happy to chat, give us a call to book your appointment. Your pet's health is our priority, and no question is too small.
