Most cats hold grudges for days up to a few weeks, depending on the perceived slight. Their memories tend to be short-term.
Bigger transgressions like rehoming, vet visits, or injury can cause cats to hold months-long grudges. Rebuild trust slowly.
Confident, easygoing cats rebound faster than anxious, clingy cats who hold longer grudges. Know your cat's temperament.
To get back in your cat's good graces, give space then offer treats, catnip, playtime, pets, and comfort.
Avoid grudges by keeping routines consistent, reading body language, and never punishing cats after the fact.
Kittens under 6 months don't hold grudges long since everything is new to them. Use this period for positive handling.
Seek help from a vet or behaviorist if your cat's grudge seems extreme or impairs your bond long-term.
