Yes, cats do get angry, and they do get scared. ... Fear and anger are among the most basic of emotions, hardwired into every mammal because those emotions are crucial for an animal's very survival in the wild. Resentment, not so much.

How long does a cat hold grudge?

Do they have memories long enough to hold a grudge? Compared to a dog's memory (which lasts no more than 5 minutes) a cat's memory can last up to 16 hours, say the researchers at the University of Michigan.

Do cats remember if you accidentally hurt them?

A one-off bad experience does not lead to a grudge. Survival instincts drive cats, so they have good memories when it comes to physical or mental trauma. Anything that jars with these instincts will linger for a long time in a cat's memory. The cat will then do whatever it takes to avoid repeat exposure.
