Why is my kitten terrorizing the older cat?

As I said earlier, kittens are just as playful as their adult counterparts. However, they have more energy, and they can be more curious.

Suppose your kitten is terrorizing your older cat. The following can be the reasons behind it.

The older cat is a submissive type.

Felines have some sort of ranking system in them. Thus, while some old cats are ready to fight when they feel pissed, some are submissive.

A submissive cat is usually the one slinking around and acts like a victim. If your kitten senses this on your older cat, it may start bullying and attacking. It’s their way of expressing superiority above the others.

The kitten is more active and curious than average.

Even modern-day house cats come from a long line of hunters. Thus, they have that hunting instinct that gets triggered now and then.

In general, felines usually get triggered by any movement they sense as prey.

Kittens are a bit more clueless than older cats. Thus, chances are they won’t stop attacking every time they see the old cat.

The kitten feels threatened or frightened.

Another reason why the kitten won’t leave the older cat will be if it feels threatened or afraid. It’s not a usual case if your senior cat is not aggressive.

However, if the kitten feels something is wrong, it may redirect its aggression towards the old cat.

The kitten is territorial.

Kittens are just as territorial as old cats. Thus, if they think they own a particular area and your senior cat always stays there, chances are it won’t stop being mean and aggressive.

Such behavior is normal and should wind down in a few months. However, if it stays like that for a long time, it may be a signal for you to take action.
