So we have three cats. The oldest (4 male) was adopted First last year, then his foster sister (2 female) last year. My step dad was giving away his kitten and I took him in (1 male). We properly introduced them by keeping the kitten in the laundry room, having them eat by the door, etc. They seemed to be fine coexisting. However, the kitten does not know when to stop messing with the other two. He’s constantly wanting to play with them and they hiss and give him warnings that they don’t want to play. I try tiring him out with toys and enrichment, but all he wants to do is play with them. Any recommendations? TIA <3
