@YvetteColomb he's very cute and VERY loud! We don't think our "guest" cats are very fond of him, too; the one who's more outgoing seemed pretty unhappy about the kitten toddling around in his space

I'm hoping the glass I got for the top of the tank can be made useable. I forgot to consider before going out looking for it that everyone wants plexiglass right now for making cashier shields, so I had to get regular window glass. I'm going to attempt to "laminate" it to make it safer to use, and will likely replace it with a better solution when plexi's available again

yeh cats can be funny about accepting new cats, but introducing a kitten increases the chances of success
