Behaviours That Seem Odd but Are Completely Normal in Pets

It's one of the most Googled pet behaviors for a reason — you let your dog outside and suddenly they're grazing like a small, enthusiastic cow. The good news: this is almost always harmless. Dogs are omnivores by nature, and grass eating is a normal, observed behavior across both domestic dogs and wild canids.

While the old theory was that dogs eat grass only when they feel sick, research and veterinary observation suggest the opposite is closer to the truth: most dogs who eat grass show no signs of illness beforehand and don't vomit afterward. It may simply be something they enjoy, a source of fiber, or an instinctive behavior carried forward from their ancestors.

The bigger concern is which grass they're eating — lawns treated with pesticides or herbicides pose a real risk. If your dog has a grass-munching habit, stick to untreated areas and keep an eye on how much they're consuming.

Your cat walks up to your full glass of water, makes direct eye contact with you, and pushes it off the counter. Deliberate? Almost certainly. Malicious? Not quite.

Cats are natural hunters with a strong prey drive. Pawing at objects — especially small, moveable ones — mimics the behavior of testing whether something is alive or worth chasing. It's also a way of exploring their environment with highly sensitive paw pads. And yes, if you react with alarm every time it happens, your cat has learned that this particular move gets your attention fast.

This behavior tends to peak in younger, more energetic cats. Providing enough environmental enrichment — puzzle feeders, interactive play, and vertical climbing space — can redirect the energy. But if your cat's occasional shelf-clearing drives you up the wall, know that they're not being spiteful; they're just being a cat.

If you've kept rabbits, you've probably been startled by a sudden, loud thump from across the room — only to see your rabbit sitting calmly, apparently unbothered. What happened?

Thumping is a rabbit's primary alarm signal. In the wild, rabbits thump their powerful hind legs against the ground to warn other members of the group that a predator is near. Domesticated rabbits retain this deeply wired reflex, and they can trigger it in response to sounds or vibrations you haven't even noticed — a distant car, a dog barking outside, or a shift in air pressure.

Occasional thumping is completely normal. If it's happening constantly, it's worth assessing whether your rabbit is in a high-stress environment — near loud appliances, other animals, or heavy foot traffic — and adjusting accordingly. Chronic, persistent thumping alongside other signs of stress may warrant a conversation with a rabbit-savvy vet.

Before settling in for a nap, many dogs will spin in circles — sometimes two or three times — before dropping down. It looks unnecessary, maybe even a bit compulsive. But it's a behavior that likely traces back thousands of years.

Wild dogs would trample grass or brush to create a flat, comfortable sleeping spot, clear the area of insects or small creatures, and position themselves to face a particular direction for safety. Your dog's living room doesn't have tall grass or predators, but the instinct persists anyway — hardwired into their behavior even when the original purpose is irrelevant.

Occasional pre-sleep circling is entirely normal. However, if a dog is circling repetitively and seems unable to stop or settle, or if the circling is accompanied by signs of disorientation or distress, that's a different matter worth discussing with a vet.

Few things test a pet owner's composure like waking up to a dead mouse — or worse, a live one — deposited neatly on the kitchen floor. Your cat is not trying to upset you. In fact, quite the opposite.

Cats are solitary hunters by instinct, but when they live with people they care about, some cats appear to share their catch as a social behavior — similar to how a mother cat would bring prey to kittens to teach them. Whether your cat is genuinely trying to 'teach' you or simply share the bounty, the intent isn't cruelty; it's a kind of affection, filtered through feline logic.

Indoor-only cats may substitute toys for prey and bring those instead — which is both adorable and much easier to deal with. Providing regular interactive play sessions helps channel the hunting drive in a more cohabitation-friendly direction.

This one is genuinely unpleasant to witness, but it's more common than most owners realize. Coprophagia — the technical term for poop-eating — is seen in a significant portion of the dog population, particularly in puppies.

In young dogs, it may simply be exploratory behavior as they use their mouths to learn about their environment. Mother dogs naturally clean up after their pups by consuming their waste. In some adult dogs, the behavior persists as a habit, may be linked to dietary deficiencies, or can be stress-related. Dogs kept in confined conditions or with inconsistent feeding schedules are more prone to it.

If your dog occasionally eats their own feces and is otherwise healthy, it's more of a hygiene nuisance than a health crisis — though it does carry some parasite risk. Persistent coprophagia in adult dogs, especially if it's new behavior, is worth mentioning to your vet. Our guide to feeding schedules and portion sizes is a useful reference if dietary factors may be at play.

That rhythmic pushing motion your cat makes with their paws against your lap, a blanket, or soft furniture — often with a blissed-out expression — is called kneading, and it's one of the most endearing holdovers from kittenhood.

Kittens knead their mother's belly to stimulate milk flow while nursing. Adult cats retain the behavior and tend to perform it when they're relaxed, content, and feeling safe. If your cat kneads on you, that's generally a high compliment — you're being treated like a place of comfort and security.

Cats also have scent glands in their paw pads, so kneading on soft surfaces may also serve a mild territorial function — a way of leaving their scent on spaces that feel like home. Either way, it's a sign of a settled, comfortable cat.
