Staring into space: Cats have keen senses, so they probably saw a fly or a speck of dust.
The ready to pounce quivering butt: Cats wiggle back and forth to position themselves for the perfect attack.
Rolling back and forth: Your cat is showing submission or inviting you play.
Sticking a raised butt in your face: Tail sniffing is normal in the cat world, so this is your cats way of saying hello.
Making squinty eyes: Cats squint when they’re content. Closing their eyes slowly is a sign of trust. Try to slowly blink at your cat, it’s a friendly gesture of trust.
Cats sleep in a circle to conserve body heat.
Sitting like a cat loaf: Cats tuck their paws under them when they feel safe, and it also conserves body heat.
Kneading: This is likely a leftover trait from when they were a kitten when they did this to their mother’s stomach to produce milk. When your cat does this it is usually a warm gesture of familiarity and being content, or wanting attention.
Exposing its belly: Since the belly is the most exposed area for a cat, this is an enormous show of trust. Don’t confuse this with a cat on its back defending itself. The show of trust is letting you touch the belly.
Sitting on your computer: Cats like warm places.
Chirping or clacking at birds outside: The clicking and chattering is a sound a cat makes when it’s concentrating on a target for the hunt, they often make it out of frustration they cannot reach it.
Cats are always mindful of protecting themselves, and so they find security in confined spaces. A box is exactly that.
The “hug ‘n’ bite”: Biting and wrestling with you is actually not a sign of aggression but of playfulness. Cats forget we don’t have fur to protect us from their teeth and claws.
