Why do my older cats pick on the new kitten? How to stop it?

Updated On September 23rd, 2025

I have 8 rescue cats. From 10 yrs old to 6 months old. All have been fixed. Jet and bailey ( brother and sister) are 14 months old. But they gang up and Spartacus ( male 6 months old)! They seem to stark him all the time. Haven’t really seen them hurt him but he is scared of them .. he hides a lot. They don’t brother his sister misty,, or any of the other cats just Spartacus!!! Any ideas why ? Or what I can try to make them stop.

When you have that many cats, you are bound to have conflict at some point. They may single him out due to his age or size. Separate him for a week or two, then gradually reintroduce him. First, allow the others to hear and smell him but not see him. Progress to sight but without physical contact. Before a physical introduction, place him in a closed carrier in the room with the other cats. Once they have accepted him, you can try a supervised physical introduction. Provide an adequate number of litter boxes (typically one per cat plus an extra). An adequate number of bowls, beds and toys should also be provided to prevent resource protection. A pheromone product, such as Feliway spray or plug in diffusers, may decrease any anxiety in the home.
