How can I tell play-fighting from real fighting?

Play is quiet, reciprocal, and the cats swap positions. Real fights are loud, one-directional, and the ears stay flat. Sustained vocalisation is the clearest tell.

Why do my cats fight at night?

Cats are crepuscular — most active at dawn and dusk. Unspent energy plus territorial patrolling makes evening conflicts common in multi-cat homes.

Do cats get injured in fights?

Puncture wounds from bites abscess easily and are the most common serious outcome. Any wound that swells or weeps needs veterinary attention.

What do cat fight sounds mean?

Q: What do cat fight sounds mean?

Fighting vocalisations are loud, high-amplitude shrieks and caterwauls produced during or immediately before physical contact. They serve to intimidate the opponent and to recruit distance — most cat “fights” are noise and posturing that resolve without injury.

What it sounds like

Extended caterwauls, sudden shrieks, and overlapping growls from two animals at once.

What it means

Active conflict over territory, resources or mating access.
