Big cat and wee cat have been with us since 8 weeks old, they are now 3.5 years. Their relationship is turbulent to say the least. On the whole they tolerate each other, but swing from apparent affection to fighting. Big cat is a big soft lump, he has a chronic respiratory problem, which is well controlled but I feel like it makes him easy to pick on. They will sleep on the same bed (at opposite corners) and feed from the same bowls together without any problems. But the fighting...
It doesn't happen often, but they've had full scale screeching/hissing/fur flying disagreements. 10 minutes later, wee cat is sitting licking big cat's head like nothing happened.
I'm confused. I don't want this behaviour to escalate. Is it likely to get worse? Is there anything I can do to help them get along better?
There are no signs of stress, no inappropriate toileting or hiding or anything. They are also free range indoor/outdoor cats.
