Everyone was really quiet. Honestly, this generally does mean they're all getting along. When bad things happen they've yet learned to be quiet ... they instead tend to get insanely loud. So I expected some sort of cooperation. Here they are bonding over YouTubers. Annoying for us, but its one of the few things they all three agree on.
The cats seem to have learned from the best. When they're causing trouble, they are LOUD. When they are quiet, we can often find them cuddling.
