Sounds like you’re killing it on the litter boxes. So, does this open floor plan allow for a cat to traverse the space without touching the ground? Having vertical pathways where your cats can make an exit without getting blocked on the ground is important for side-stepping conflict. I have a very patient cat and a surprisingly gentle toddler, and they get along very well, but he’s often too excitable and loud for her. When he’s in the dining room, blocking her path and getting rambunctious, she can avoid him by jumping on the dining room table, then to an island bar counter, then down to the kitchen counter and from there exit into one of the bedrooms. Similarly, in the living room, she makes use of the back of our L shaped couch to reach the two exits if she doesn’t feel like engaging with the toddler playing on the floor. Some cat shelving, or even just some strategically placed furniture, can give them an exit route (doorways are tough, but maybe a small end table they can jump up on or something? Difficult to say without walking through your house).
It sounds like you’ve got a lot of enrichment for the younger guy. The only thing I could possibly suggest would be adding more structure. You could try playing until he gets exhausted in the morning, then do his morning feeding, which would probably get him to burn some energy and do a big morning nap. Then do the same thing at night to get him to calm down for bed. For all I know you’re already doing this, but it’s all I can think to suggest. It definitely sounds like the younger guy is instigating out of boredom and the older guy is just is not having it.




The song you play to summon that statue is called, “The Elegy of Emptiness.” Make of that what you will.
