Myths About Neutered Cats – What Really Happens

Cat sterilization is a topic that, although increasingly common, still raises doubts and mixed opinions. Many of these concerns stem from outdated beliefs or a lack of updated information.

We know that deciding whether to sterilize your cat is not something to take lightly. As caretakers of their well-being, we want the best for them—and that means being well-informed. That’s why we’ve also addressed this issue in depth in our blog article Is It Advisable to Neuter My Cat?, where we explain the procedure, post-op care, and veterinary recommendations.

In this new article, we focus on the most common myths that still circulate about sterilization. Some are deeply rooted and may influence your decision. That’s why we tackle them with clear, balanced, and evidence-based information—to help you make a well-informed choice with your vet.

Myth 1: Neutering a cat is cruel or unnatural

A widespread belief is that sterilization goes against the animal’s nature or “takes away its essence.” In reality, it’s a routine veterinary procedure that can improve the cat’s quality of life.

Benefits: Prevents health issues like uterine infections, mammary tumors, or aggression in males. Also helps control overpopulation.

Considerations: It’s still a surgical procedure under anesthesia, which carries some risks like any surgery. It must be performed by qualified professionals with proper follow-up.

Myth 2: Cats gain a lot of weight after being neutered

It’s true that metabolism changes and energy needs decrease after sterilization.

Reality: If diet isn’t adjusted and exercise isn’t encouraged, weight gain can occur.

Solution: With a specific diet for neutered cats and daily playtime, a healthy weight can be maintained. At Picart, we’ve written about:

Myth 3: Sterilization changes their personality

Many believe their cat will no longer be the same after being neutered.

What usually happens: Hormone-driven behaviors (marking, mating calls, aggression) decrease, but the cat’s core personality (playful, affectionate, independent…) remains unchanged.

Important: Some owners even notice calmer and more affectionate behavior, though every cat is unique.

Myth 4: It’s better for her to have at least one litter before being sterilized

This idea has no scientific backing.

Reality: Sterilizing before the first heat can drastically reduce the risk of certain cancers, like mammary tumors, and prevent uterine infections.

Myth 5: Males don’t need to be neutered

It’s a mistake to think only females should be sterilized.

Benefits for males: Reduces fights, urine marking, disease transmission, and contribution to unwanted litters.

Benefits and potential risks of sterilization Common benefits:

• Prevention of tumors and reproductive diseases
• Reduction of unwanted behaviors
• Improved household harmony
• Control of feline population
• Longer life expectancy

Possible risks or side effects:

• Weight gain if diet isn’t adjusted
• Requires surgery under anesthesia (low but present risk)
• Possible behavioral changes if post-op environment isn’t well managed

What to consider before deciding

Sterilization is an important decision. That’s why at Picart we encourage you to discuss it with your trusted vet, weigh the pros and cons, and choose what’s best for your cat, your family, and your lifestyle. Every cat is different, and what works for one may not be ideal for another.
