As the movie demonstrates, when these little critters aren’t sleeping, they’re practicing how to walk and run. They prefer to hide out in the “cave” of an old cat gym we left for them but we decided to lock them up in a cat carrier overnight. This is to protect them from their father (Tomcats are known to kill kittens because they’re a future threat) and possible coyotes. The quartet can’t get out, nor can anything get in, unless the predator has developed opposable thumbs. Normally their mother is locked up with them too. Princess was nowhere to be found last night though.
Their current names are temporary placeholders. I pushed for The Thundercats (the Eighties version, not the ongoing re-imagining). It’s not hard to feminize the names of the key characters in my opinion. Due to their mother being mis-labeled Buttercup, I considered The Princess Bride yet gave up since those names don’t convert as well.
