I can't remember if I posted this photo before and am being too lazy to go look. It's a pretty accurate depiction of the cats as Yuu is being active, and talkative, while Eevee looks like he wonders what he did wrong to be treated like this. We've never had more than one cat at a time before so it's been interesting watching them interact.
Which brings me to the thing I find both funny and incomprehensible when they "fight". What is it about toes? They'll be in a stand-off for a bit and then each will try to nip the toes of the other. Neither succeeds, but it gives the impression that it is an attempt to score points in the contest, or something like that. EK and I tried to look online to see if any cat experts had an explanation, but it wasn't a topic that others seemed to have thought about so there weren't any answers.
