Two of my cats are ganging up on another

We have three cats and they all got along, but we left for awhile and when we came back two of three started really disliking one of them, and what could be causing this?

Hi
Why this happens is often a mystery to us humans but it is a common issue. It may be what is known as aggression trauma. this is when something frightens a cat and they take out their fear on another cat even if if it had nothing to do with them. So it could be a loud bang or do other thing which may have triggered a fearful reaction.

The best way to help your cats is to take them through a period of re introduction. It does take a little time and effort but is the best way to help your cats get back to how they were.

the process is described here
