7 Weird Cat Behaviors You're Not Sure About 

Head-Butting: When your cat gently bumps their head against you, it's a sign of affection and trust. It's their way of marking you with their scent.

Tail Quivering: A quivering tail usually means your cat is excited or happy to see you. However, in some cases, it could also signal overstimulation.

Purring: While purring is often associated with contentment, cats can purr when they're in pain or stressed, too 

Biting or Nipping: Cats may lightly bite or nip when they're playing or want your attention. It's their way of saying, "Let's interact!"

Hiding: Cats sometimes hide when they're feeling unwell or stressed. It's a survival instinct to find a safe, quiet place away from potential threats.

Cat Zoomies: These sudden bursts of energy, often accompanied by running and jumping, are common among cats 

Chirping or Chattering: Some cats make a chirping or chattering sound when they spot birds or squirrels through a window.
