My sister is home and she brought her cat.He is 8 years old.I have a kitten that is 3 months old.My sister’s cat is mean to my kitten what do i do?

Sometimes when cats don’t get introduced properley, they never get a long. Also, like humans, some cats just don’t like the personality of the other cat. They may never like each other. You should keep them in seperate rooms. If your sister is only there for a vistit, you should probably put her cat in just one room because you kitten probably already made his territory. If your sister’s cat is there to stay, you should somehow seperate the house in half so your sister’s cat makes a territory and eventually get rid of the divider in maybe, about a month. Then hope that they stay in their own territory and don’t go together and fight.

when your sisters cat comes home put your kitten in his own space with a door so the cat wont hurt her

maybe seens your sister is visting maby you should show honer to her and but your kitten your room.

I think the most sensable thing to do is to separate the cats and maybe after a little while they will start to like each other!
