8 Strange Cat Behaviors You Probably Didn’t Know About

Jan 1, 2026byEmily Dawson

Cats are mysterious creatures who often leave us scratching our heads at their quirky antics.

From knocking things off counters to making strange chirping noises, our feline friends have some truly puzzling habits.

Understanding these behaviors can help you connect with your cat on a deeper level and appreciate the wild instincts still alive in your furry companion.

While these behaviors are generally normal, if your cat shows sudden changes in behavior or seems distressed, consult your veterinarian to rule out any health concerns.

Ever noticed your cat making rapid, high-pitched chattering sounds while staring at birds outside?

This fascinating behaviour is deeply connected to their hunting instincts.

When cats see prey they can’t reach, they experience a mix of excitement and frustration that triggers this unique vocalization.

Some experts believe the chattering might be an involuntary jaw movement, preparing for that perfect killing bite they would deliver in the wild.

Your peaceful sleep gets shattered by thundering paws racing through the house at ungodly hours.

Cats are naturally crepuscular, meaning they’re hardwired to be most active during dawn and dusk.

These sudden energy bursts, affectionately called zoomies, are completely normal for your feline friend.

Try increasing daytime play sessions and engaging your cat right before bedtime to help shift their energy schedule.

3. Knocking Everything Off Tables

That satisfying crash of your water glass hitting the floor at 2 AM?

Your cat planned that.

Wild cats use their paws to test whether prey is alive or dead, and this instinct carries over to household objects.

Your reaction to the chaos actually reinforces the behavior, teaching your cat that knocking things over is an excellent way to get attention when they’re bored.

4. Making Biscuits With Their Paws

When your cat rhythmically pushes their paws against you or a soft surface, they’re reverting to kittenhood.

Baby kittens knead their mother’s belly to stimulate milk flow during nursing.

Adult cats continue this comforting behavior when they feel safe and happy.

Plus, scent glands in their paw pads release pheromones, marking you as their treasured territory and reinforcing your special bond.

5. Bringing You Dead Animals Or Toys

Finding a deceased mouse on your pillow might seem horrifying, but it’s actually a compliment.

Mother cats teach their kittens hunting skills by bringing them prey, and your cat views you as family.

By presenting these gifts, your feline friend is either trying to teach you essential survival skills or sharing their successful hunt as an act of genuine affection and trust.

6. Obsessing Over Boxes And Your Laptop

No box is too small for a determined cat to squeeze into.

Enclosed spaces trigger a deep instinctive need for security and warmth, providing protection from potential predators.

When your cat sits on your laptop or book, they’re claiming items that smell like you, mixing their scent with yours to strengthen your bond and declare ownership over both you and your belongings.

7. That Adorable Tail Quiver

A cat approaching with an upright, gently quivering tail is displaying pure joy.

This endearing behavior commonly appears when greeting their favorite human after being apart.

Unlike the stiff tail position that precedes spraying, this soft vibration signals excitement and deep affection.

Think of it as your cat’s version of an enthusiastic tail wag, showing how thrilled they are to see you again.

8. Grooming Your Hair Like A Fellow Cat

Waking up to your cat enthusiastically licking your hair might feel weird, but it’s incredibly sweet.

Cats groom each other to strengthen social bonds within their colony, and they’re treating you as a valued family member.

The texture and scent of damp hair especially triggers their natural grooming instincts, while the act itself helps them mark you with their scent, reinforcing your special relationship.
