wondering is this happy or mad?

[hrmom26]

my bun has a habit of picking up the corner of his litter box and dropping it, he does this over and over making a loud thump noise lol is this i'm angry pay attention or is this i'm just playing around? just curious thanks

Could be both. Could be he doesn't like the litter box there and wants to move it, is bored, or anxious for feeding time, or maybe he likes the sound of it thumping on the ground. Rabbits are just strange

Nora likes to squish herself around her litter box and nudge it out of the corner or sometimes she tries to pick it up with her teeth like she's gonna toss it. Not sure what she's trying to accomplish, lol. Faye will also pick up and throw toys/dishes both playfully and angrily. It really can mean anything
