Yep, they can be litter trained. Not sure if coating things in an apple spray (something rabbits find gross) counts as training them not to chew stuff. Rabbits are pretty clean and are suitable as house pets.

I’ve seen YT videos of one playing basket ball and learning to signal for food and such. Mine used to push a ball back and fourth between me and them. Saw someone else also train a rabbit to high-five them. It’s also possible to be able to call them (although you might need to use a more arbitrary sound than a name, like squeal a certain tone or a whistle.)
