Cat Behavior Resources

Cats peeing or pooping outside the litter box is usually a symptom of a medical or environmental issue.

Some common causes include:

• Urinary tract inflammation or infection

• Bladder crystals or stones

• Arthritis, which can make getting into the box painful

• Stress or anxiety

• Pain during elimination, so the cat starts avoiding the box

• Changes in the litter box setup, like moving it, switching litter type, or not keeping it clean

• Conflict with other pets, especially in multi-cat homes

If using the box hurts, cats often learn to associate it with discomfort and will look for safer places instead. The good news is that with a little detective work, most litter box issues can be fixed. Start with a vet check to rule out medical causes and then make the environment feel calm and comfortable for your cat.

Scratching is a normal feline behavior with multiple functions:

• Marking territory (cats have scent glands in their paws)

• Claw maintenance and stretching

• Stress relief and muscle conditioning

If they won’t stop scratching, they need appropriate outlets like posts or pads.

Aggression is a communication style with many possible triggers:

• Play aggression—natural predatory play without bite inhibition.

• Fear aggression—responses to unfamiliar people, animals, or situations.

• Redirected aggression—arousal from something the cat can’t access.

• Pain-related aggression—illness or discomfort makes handling unpleasant.

• Territorial aggression—defending space against intruders.

A veterinary check can rule out pain or disease before addressing behavioral triggers.

Cats vocalize for many reasons. They meow mainly to communicate with humans, not other cats, and excessive vocalization can indicate:

• Hunger or meal anticipation

• Attention-seeking

• Stress or anxiety

• Medical issues (e.g., thyroid disease, cognitive changes in older cats)

Meowing at night or repeatedly often relates to hunger cycles, discomfort, or environmental stressors.

Cats’ play behavior closely mimics predatory sequences (stalk, pounce, bite). If a cat hasn’t learned bite inhibition (often learned from littermates), they may bite humans during play. Providing predatory-style toys on poles and scheduled play sessions helps channel this behavior appropriately.

Hiding can be normal in short bursts, but persistent hiding often signals:

• Stress or anxiety

• Fear of stimuli (loud noises, new environment)

• Pain or medical illness

• Environmental change (new home, new people or pets)

Cats hide to feel safe and secure when overwhelmed. If paired with other signs like not eating or lethargy, a vet check is recommended.

• Cats purr by vibrating muscles in their voice box and diaphragm, producing a low-frequency sound during both inhaling and exhaling.

• They purr for many reasons, not just happiness — including contentment, bonding, self-soothing, and even stress or pain.

• Kittens purr to communicate with their mother, and adult cats may use a special “solicitation purr” to get attention from humans.

• Some research suggests purring’s low vibrations may also have healing or pain-relief benefits, though this is still being studied.

• Kneading starts in kittenhood, when kittens press on their mother to stimulate milk, and many cats carry this comforting behavior into adulthood.

• Adult cats usually knead when they feel safe, relaxed, and content, making it a common self-soothing behavior.

• Cats have scent glands in their paw pads, so kneading can also help mark a person or place as familiar and secure.

• It may also be an instinctive way to prepare a soft resting spot, a behavior inherited from wild ancestors.

In most cases, kneading is a normal, positive sign of comfort and trust.

Cats knock things off counters because of instinct and learning — not spite:

• Natural hunting instincts: Swatting objects helps cats test movement, sound, and texture, similar to how they’d explore prey.

• Curiosity: Cats use their paws to investigate new or interesting items and see what happens when they touch them.

• Attention-seeking: If knocking something over gets a reaction (even a negative one), cats may repeat the behavior.

• Boredom or excess energy: Without enough play or enrichment, everyday objects can become entertainment.

In short, it’s a normal cat behavior driven by curiosity, instinct, and the need for stimulation.

When a cat shows its belly, it often means trust and relaxation, but it’s not automatically an invitation for belly rubs — context and body language help you read what your cat really means.

• Sign of trust and comfort: Showing the belly exposes a cat’s most vulnerable area (where vital organs are), so a relaxed belly display usually means your cat feels safe, secure, and trusts you and their environment.

Not always an invite to pet: Even if it looks like a belly rub invitation, most cats do not want their belly touched — reaching for it can trigger a defensive response because the belly is sensitive.

Can be playful or relaxed: Sometimes a cat shows its belly during play, stretching, or simply because they’re relaxed.

Context matters: Look at their overall body language — relaxed eyes, loose posture, and slow blinks usually mean comfort, while tense muscles or twitching tails suggest they may be ready to defend themselves.
