A cat that bites "out of nowhere" almost always sent signals first. Learn to spot them and you'll have a cat that "communicates well."
The big four signals
- Tail — held high means happy, swishing fast means agitated, low and tucked means scared
- Ears — forward is curious, flat is angry or scared, sideways "airplane mode" is overstimulated
- Eyes — slow blinks are affection, dilated pupils mean arousal (good or bad), narrow pupils with a fixed stare means tension
- Posture — loose and stretchy is content, tight and crouched is preparing for something
The shift from "enjoying being petted" to "had enough now" is often a single twitch of the tail. Stop petting at the twitch, not the bite.
Combining signals for the full picture
No single signal tells the whole story — a swishing tail with relaxed ears during play is very different from a swishing tail with flattened ears and dilated pupils. Read the whole body together, and when signals conflict or escalate quickly, give space rather than trying to interpret further.
Vocalisations worth knowing
A short chirp or trill is usually a friendly greeting. Yowling can signal distress, a territorial dispute with another cat, or, in older cats, cognitive changes worth mentioning to a vet. A low, sustained growl is a clear warning to back off, not a sound to push past.
