We have 4, and the older longhaired calico is also the facilitator and wannabe momma cat. It’s actually rather impossible not to notice the social/almost pack bond aspect of things with cats if you have a good “alpha”. Cats, loners? No way...
Interesting point. In my pride the dominant one is a loner, so there’s no facilitator. Probably why the two subs have bonded, but not the pride as a whole.
