"But My Pet Is Different" — And 6 Other Spay/Neuter Myths We Need to Talk About

We've heard them all.

"She's an indoor cat." "He's a purebred." "I'll do it eventually." "It just feels wrong."

These are the reasons people give for not spaying or neutering their pets — and we get it. Most of them come from a place of genuine love. But most of them are also based on outdated information, old-school thinking, or just wishful reasoning.

So let's clear the air. Here are the seven most common myths about spay and neuter — and the truth behind each one.

Myth #1: "My pet is indoors. It doesn't matter."

This one sounds logical, but here's the thing: animals escape. Doors get left open. Windows have gaps. That one time your cat slipped past you at the door? It happens to every pet owner eventually.

Beyond the escape risk, an unspayed female still goes into heat — whether she ever meets another cat or not. Heat cycles can mean yowling, restlessness, and stress for weeks at a time. And an intact male still has the hormonal drive to roam, mark, and find a mate. That behavior doesn't disappear just because they live inside.

Spaying or neutering isn't just about preventing unwanted litters. It's about your pet's health and quality of life — indoors or out.

Myth #2: "It's better to let her have one litter first."

This is one of the most persistent myths in pet ownership — and there's simply no medical evidence to support it. Veterinarians are clear: there is no health benefit to allowing a female dog or cat to have a litter before spaying.

In fact, the opposite is true. Spaying before the first heat cycle dramatically reduces the risk of mammary cancer. The longer you wait, the higher that risk climbs.

One litter also means finding homes for multiple puppies or kittens — which sounds manageable until you're three weeks in and still have five animals who need a place to go.

Myth #3: "My pet is purebred, so it's different."

Purebred animals are not immune to overpopulation. Breed-specific rescues exist for a reason — they are full of purebred dogs and cats who lost their homes or were bred irresponsibly.

Unless you are a licensed, responsible breeder with health-tested animals and committed buyers already lined up, breeding your purebred pet contributes to the same problem as any other unplanned litter. And even responsible breeders spay and neuter animals not intended for breeding.

Pedigree doesn't protect an animal from ending up in a shelter.

Myth #4: "It will change my pet's personality."

This fear is understandable — nobody wants to alter the animal they love. But what spaying and neutering actually changes is hormone-driven behavior, not personality.

Your dog's goofy joy, your cat's quirky habits, their love for you — none of that comes from reproductive hormones. What does? Roaming, aggression, territory marking, and the anxiety of heat cycles. Removing those stressors typically makes pets calmer, more focused, and more bonded to their family.

Your pet will still be exactly who they are. Just with less drama.

Myth #5: "It's too expensive."

Cost is a real barrier — and we take it seriously. It's exactly why PennyFix exists.

But here's something worth considering: if you're already stretched thin caring for one pet, an unplanned litter doesn't just add mouths to feed. It adds vet visits, vaccines, deworming, and emergency care for however many puppies or kittens arrive — multiplied by the size of the litter. The cost of one spay or neuter procedure is almost always far less than the cost of caring for even a single litter. Skipping it to save money now can easily cost far more later.

We fund grants to veterinary clinics, shelters, and rescue organizations across the country to make spay and neuter procedures free or low-cost for people who need help affording them. We've helped fund nearly 10,000 procedures since our founding, and 100% of every donation goes directly to that work.

If cost has been the reason you've been waiting, reach out to your local humane society, low-cost clinic, or a grant organization. Help may be closer than you think.

Myth #6: "One litter won't make a difference."

We understand the math doesn't feel dramatic when you're looking at one cat or one dog. But consider this: an unspayed female cat and her offspring can produce thousands of kittens over a few generations. A single unplanned litter often leads to another, and another, as those offspring reproduce too.

The overpopulation crisis in shelters isn't caused by one irresponsible owner. It's caused by millions of people thinking exactly this — that their one situation is too small to matter.

It's not. Every single procedure makes a difference.

Myth #7: "I'll get around to it."

This is the one that quietly causes the most harm. Not bad intentions — just delay.

Here's something people don't think about: even when you finally decide to make the appointment, your vet may not have an opening for weeks. Clinics are busy. Low-cost spay/neuter programs often have waitlists. "Getting around to it" doesn't mean it happens the next day — it means you're now weeks or months further down the road than you already were. And a lot can happen in that time.

A cat can go into heat as early as four months old. A dog can become pregnant on her first cycle. "Eventually" has a way of arriving before you're ready, and by then, a litter has happened that nobody planned for.

The best time to spay or neuter is as early as your vet recommends — often between four and six months of age. The second best time is right now. Make the call before you think you need to.

The Bottom Line

Every myth on this list has one thing in common: it's a reason to wait. And waiting is how the cycle continues.

Spaying and neutering is safe, routine, and one of the most impactful things you can do for your pet and for animals everywhere. If cost is the barrier, help is available. If it's fear or uncertainty, talk to your vet.

And if you want to help other animals get the care they need, PennyFix makes it simple. Every dollar you donate goes directly to funding spay and neuter procedures for pets whose families need a hand.

Because the myths are just excuses. The animals are very real.
