The boys playing... they're a handful! Had to put my plants very high and out of the way. Ninja loves to perch on everything! Ninja considers sink scouring pads, washclothes and a new/unused poop scooper as "prey", taking it and running off with it - although they have every kind of toy imaginable and cat grass! They also love to chase each other at top speed - running across the top of the couch, tables, etc. Ninja even jumped on my PS5 chasing Tripp! Tripp jumped on my bed and climbed up on the window screen. In the past I had pretty chill kittens/cats who understood and respected boundaries, so I'm quickly deducing these guy's personalities and using methods that I learned from reliable online sources on how to deal with these issues. I love these guys, so they're well worth the effort!
