When your cat goes around giving everyone in his path a powder puff for no reason, it doesn’t necessarily mean he’s aggressive. There’s one in every multicat household and through no fault of his own, he’s labeled the “bully cat.” When we add more cats to an already established group, it causes a shift in the cat hierarchy. The shift may be as obvious as a stare down and a brawl with fur flying or it may be very subtle, such as blocking the pathway to a litter box. The resident high ranking cat may or may not relinquish his title as top cat … at first, or maybe never.
Mr. Jack, watch your back!
But that doesn’t stop the cat with ambitions to keep trying by asserting his dominance to the rest of the clan through undesirable behaviors. This could include anything from relentlessly ambushing and chasing a timid, docile cat, guarding litter boxes, taking ownership of toys, games, sun puddles and refusing to time share.
