I also have four. My limit used to be TWO, but as each extra one was rescued and needed a home, I gave in and brought them into my life.
Not a day goes by that I do not have a barf mess to clean up. Sometimes they will get their rump too near the edge of a litter box and actually mess on the floor. And I have my share of cat scars here and there. But you can’t beat the feelings you get when one wants to play hide and seek with you. Or follows you from room to room. Or wants to snuggle in your lap.
I totally belong to them.
This cat behaves like a dog with an attitude. Someday will really miss him.
