When cats know that they have made a mistake, they may show the following behaviors:

1. Some cats will choose to flee the scene quickly after making a mistake to avoid the owner's blame. They may hide under the bed, behind the sofa, or in other hidden places to temporarily avoid their owner's sight.

2. Cats’ tails are an important reflection of their emotions. When cats feel guilty or scared, their tails may hang low or even be tucked between their legs, showing a state of uneasiness or shame.

3. Cats are very sensitive animals and they can sense the emotional changes of their owners. When cats make mistakes, they may avoid eye contact with their owners to avoid exacerbating their owners' dissatisfaction.

4. When some cats are nervous or upset, they will lick or comb their hair to calm down. This behavior may also be a way for cats to try to relieve tension after making a mistake.

5. Some cats may whine softly after knowing that they have made a mistake to express their regret or ask for forgiveness from their owner.
