Why Does My Pet Do That? 10 Weird Habits Explained
Ever caught yourself thinking, “Why Does My Pet Do That?” after spotting yet another weird pet habit? Strange dog behaviours and odd cat quirks can stem from emotions, health, or even things they’ve learnt.
This guide explains ten of the most puzzling actions—helping you spot what’s normal pet behaviour and when something may need a closer look. Some answers might surprise you!
Key Takeaways
- Pets show odd habits like tail chasing, kneading, eating grass, or chirping. Most of these actions come from nature, learned behaviour, stress, or boredom.
- Cats knead when happy and mark their area using scent glands in their paws. Dogs may eat grass to settle the stomach but often just out of habit; if this happens daily, a vet check is best.
- Chasing tails in dogs can mean play or anxiety. Tail chasing might need attention if it becomes non-stop or obsessive.
- Too much barking or hiding could mean fear, illness, boredom or even diet problems. Sudden changes in habits need a visit to the vet for safety reasons.
- Experts like Petrina Firth (Pet Professional Guild/APDT UK) help with tough problems such as separation anxiety and excessive barking using gentle training and emotional checks.
Why Does My Dog Follow Me Everywhere?

Dogs are social creatures. They stick to their humans like glue, much like little shadows with wagging tails. Puppies see their owners as parents from the moment they open their eyes.
This deep bond comes from imprinting and classical conditioning—think Pavlov’s dogs salivating at a bell, only your dog gets excited by your footsteps. Many dogs follow you for safety, comfort or just a sniff of whatever you’re up to.
Separation anxiety is another culprit behind this shadow-dog behaviour. Dogs get anxious if they think you might vanish out the door without them. Some even whine or bark if left alone too long—a sign that attachment has gone into overdrive.
Extra walks help release pent-up energy and reduce worry in nervous pups. Ignoring clinginess now and then trains a dog to grow more confident on its own turf, though make sure routines stay steady so Fido knows what comes next in his day-to-day sniffs-and-wags schedule.
Why Does My Cat Knead?
Soft paws press in and out, up and down. Cats knead for comfort, just like a warm hug from mum. Kittens begin this strange habit early on, pawing at their mother’s belly to get milk flowing.
The action sticks with them even after they grow up. Kneading often happens when your cat feels happy or safe—on your lap, a cosy jumper or that one blanket you swore was yours. “It’s my space now,” says the feline language of kneading.
This quirk is more than just cute—cat paws have scent glands called vibrissae between their toes. Every push leaves behind a subtle whiff marking its territory without any stink or fuss—a secret handshake only cats can smell! Felines also use this motion to self-soothe if life gets stressful; it calms them before sleep or when anxious thunder rattles outside.
Providing soft spots meets their natural urge and shows they trust you fully—only true companions get the ‘biscuit-making’ treatment from a content cat.
Cats make biscuits not because they’re hungry, but because they're home.”
Some dogs eat grass for reasons far different from these gentle feline habits…
Why Does My Dog Eat Grass?
After cats knead like they are making dough, dogs munch grass as if it is a salad bar. This strange dog behaviour worries many owners. Some pets just like the taste or texture—grass is crunchy and fresh, after all.
Others chew on it due to boredom, not hunger. Sometimes, domestic dogs eat grass to settle an upset stomach or make themselves vomit when feeling ill.
Persistent grazing can signal something deeper—a diet problem or even pica, which means eating things that are not food. Experts see this in puppies and older companion animals alike.
If your pooch gobbles down large amounts daily, a vet visit is wise; illnesses such as malabsorption issues or food intolerance sometimes sit behind this habit. Grass eating also appears more in certain seasons—hay fever time hits some canine friends hard! Keep watch for sudden changes in dog behaviour meaning there could be hidden health trouble brewing under those whiskers and wags.
Why Does My Cat Chirp?
Cats chirp, and it often sounds like a bird stuck inside your house. This strange sound is one of the weird things cats do when they spot prey, such as birds or squirrels outside the window.
Your cat might move its jaw quickly and let out short, high-pitched noises, almost like a mumble mixed with excitement. Experts think this pet behaviour explained traces back to their wild instincts—chirping mimics hunting chatter in nature.
Many vets say cats also chirp to talk to people or other cats about what they see. Sometimes their eyes go wide while their tail flicks from side to side—they are on high alert. Chirping can signal frustration because there’s prey nearby that they cannot catch due to a closed window or fence.
If you notice your cat making these funny sounds during playtime at home, it means your feline friend is showing off strong predatory skills and healthy curiosity—a common cat quirk linked closely with natural hunting drives!
Why Does My Dog Chase Its Tail?
Dogs often chase their tails for simple fun or as a quick burst of exercise. A spinning dog can look like it’s just having a good time, burning off extra energy. Many puppies do this—just like children run in circles when bored.
Boredom is a big driver too, especially if walks and toys are missing from the day. Some dogs enjoy tail chasing because every spin seems new, keeping their minds sharp and alert.
Often, they dash after that wagging tail to get your attention—watch how fast you react! If you laugh or shout “Oi!” your cheeky pup learns to repeat the act for another show.
Dogs may also chase due to itchiness around their hindquarters, sometimes linked with allergies or skin problems—kind of like scratching an unreachable spot. In rare cases, this habit becomes compulsive; you might see your dog doing it over and over without stopping.
Anxiety and stress can make things worse—even loud noises could set them off spinning again. Pay close attention to patterns: Is it happening only at certain times? Does food change help? Use your eyes and ears—the clues are there.
“If dogs could talk, perhaps they’d ask why we twiddle our hair while thinking.”
Why Does My Cat Hide in Small Spaces?
Cats squeeze into small places because it makes them feel safe, like having their own tiny fort. These snug spots give comfort during anxiety or loud noises, such as storms or visits from strangers.
Out of everyone in the house, cats might disappear behind sofas or under beds at the first sign of trouble, seeking shelter to observe without being spotted themselves. This is normal pet behaviour rooted in survival; wild cats hid to avoid threats long before they became our companions.
Sometimes a cat in hiding may not just be shy—it could signal illness or discomfort. If your usually bold tabby starts sleeping inside cupboards for days on end, keep an eye out for changes in food intake and energy levels.
To help your cat feel content and reduce stress-driven escapes, provide cosy hideaways around the home using cardboard boxes or soft baskets. Cats love these nooks for exploring too—their curiosity runs deep! Mother Nature made felines secretive; understanding such quirks unlocks more joy with every purr and head bump.
Supplementary insights into pet behaviours
Strange habits can have simple causes, like how dogs learn tricks through rewards or why cats love to rub their faces on your leg. Science helps us spot what’s normal and what might need a closer look, so curiosity really does pay off.
Why does my pet twitch in their sleep?
Most pets twitch in their sleep because they are dreaming. Their brains send signals to the muscles, making paws jump and whiskers wiggle. Dogs may let out a soft bark or grunt, as if chasing something in dreamland.
Cats might flick their tails or move their ears while sleeping.
This behaviour is normal for both puppies and adult dogs, as well as cats. Genetics, emotions and physical health all play roles here. Pet experts say these strange dog behaviours rarely mean illness.
Still, watch for signs like tremors that do not stop or look painful—then see your vet right away to check physical health or potential trauma risks.
Why does my dog kick its hind legs after doing its business?
Dogs often kick their hind legs after doing their business to mark territory. This strange dog behaviour goes way back to wild ancestors, who used this action as a message board for other animals.
Scent glands in the pads of the paws help leave a calling card—think of it as dog graffiti—spreading smell further through disturbed soil or grass. Wild dogs would also try to hide stool from predators by kicking dirt over it, adding another layer to this weird pet habit.
Sometimes your dog wants everyone nearby (and even miles away, in his mind) to know “this patch is mine.” Kicking can show dominance and make a bigger scent statement than just toileting alone.
If your four-legged friend kicks up half the park every time he visits, though, that might signal boredom or compulsive behaviour instead of simple marking. Try more playtime and physical activity if this becomes excessive; operant conditioning or positive obedience training helps curb these odd urges too.
Why does my dog bark excessively?
Kicking up dirt or grass is just one of many strange dog behaviours, but barking too much can leave owners puzzled. Excessive barking often shows frustration, fear, excitement, or the need for attention.
Some pups shout when bored while others bark if they spot a squirrel outside or hear odd noises. Dogs dealing with separation anxiety may also become quite loud.
Many experts say inadequate stimulation can spark non-stop yapping. Try teaching simple commands like "Hush" using associative learning—Pavlov conditioned his dogs, and so can you—with patience and treats at hand.
Keep an eye out for triggers like strangers passing by or hunger pangs tied to pet food changes. Spotting these habits early helps prevent barking from becoming your home’s daily soundtrack.
How to Address Unusual Pet Habits
Some pet behaviours seem odd, yet each has a reason. Learning about these strange dog behaviours and common cat quirks can help you support your furry mate.
- Speak to a behaviour consultant for pets who can assess emotional stress, aggression or anxiety.
- Provide interactive toys to stop boredom-related chewing or chasing—these redirect strange dog behaviours in a playful way.
- Change up walks, games and toys often to keep your dog’s mind busy, especially if barking or tail-chasing increases.
- Check your dog's food label for artificial colourants—these may add to hyperactivity and make weird pet habits worse.
- Watch how much grass or soil your dog eats; it sometimes signals missing nutrition in their diet, so try switching foods if needed.
- Clean litter trays and mark spots often since cats may display bunting or hide if things smell “off.”
- Comfort your pets during sleep twitches; these can be normal dreams but sometimes hint at nightmares or senility in older animals.
- Give plenty of safe spaces for cats who hide—a small box near you helps reduce stress from noise or guests.
- Talk with your vet about seasonal allergies if scratching seems non-stop—it is not always flea-related, and some breeds are prone to itchiness.
- Avoid harsh discipline when you ask “why does my dog act weird”—positive reinforcement works best for changing stubborn habits like excessive barking.
- Make eye contact only if your pet seems relaxed; staring may scare some cats or dogs and trigger hiding or defensive acts.
- Track new habits—if anything looks sudden (like odd sleep positions), write notes before visiting the vet for proper pet behaviour explained advice.
Tips for Encouraging Positive Pet Behaviour

Every pet can learn good habits with patience and the right tricks. Strange dog behaviours, like tail-chasing or eating soil, often have simple fixes.
- Use consistent training so your pet learns what you want. Praise them with a kind word, not just treats, to avoid reinforcing bad habits.
- Keep your tone firm yet friendly to signal expectations clearly. Dogs and cats both respond well to clear cues.
- Offer mental stimulation through toys, games or puzzle feeders. Bored pets chew shoes or bark for no reason.
- Feed high-quality dog food with meat or fish as the main ingredient. This helps digestion and keeps skin healthy.
- Give plenty of exercise every day. A tired pet is less likely to dig through the rubbish bin or bark at nothing.
- Set up a safe space for your cat or dog, like a corner bed or box. Pets that hide in odd places usually feel nervous.
- Ignore minor oddities unless they cause harm. Pet behaviour explained in many cases boils down to stress or playfulness.
- Redirect strange habits gently; toss a ball if your dog chases its tail, offer tactile distractions if your cat kneads too much.
- Socialise puppies and kittens early with people and animals to curb future issues.
- Schedule regular check-ups at the vet if new quirks pop up suddenly, as health issues sometimes mask as mischief.
When to Consult a Pet Behaviour Specialist
After using new tricks to encourage positive pet behaviour, sometimes odd habits linger. A dog might bark non-stop or a cat could start attacking shadows. If changes in routine, more playtime or treats do not help, this may signal something deeper than just strange dog behaviours.
Pet trainers like Petrina Firth, Certified Animal Behaviourist and CSAT expert, often step in here. She has over 10 years’ experience working with unusual cases such as separation anxiety and excessive barking for the Pet Professional Guild and APDT UK.
Emotional assessments can reveal hidden triggers no one spotted. If your pet’s eating grass becomes constant or tail chasing leaves them dizzy daily, it is time for expert help. The right specialist makes sense of habits that seem puzzling yet distressing—bringing calm back into the home with real solutions instead of guesswork about normal pet behaviour.
