Most cats are susceptible to cat traps (aka cardboard boxes), and Oscar is no exception. I think he’s actually more attracted to them than the average house feline, given the speed at which he appears in them once they’re opened. He set a new record today; in fact, I’m pretty sure he teleported into this one.
Seriously, it took three seconds: open box, remove item, behold kitten in box. Being a contrarian like all felines, he hasn’t touched it since I put it in the floor for him, but I suspect it will become a receptacle for milk tops or toy mice by morning.
