I have a 13 week old Havana rabbit mix (i was told he’s mixed with netherland dwarf but there’s just no way). He’s a free roam bunny in my fairly large bedroom. I have a large play pen for him that houses his food, some toys, litter box, and hidey house. The play pen is always open unless i’m asleep. He used to come and explore the room every night but lately he refuses to leave the play pen. He only plays in there even when his toys are outside of it. Is there any way to encourage my bub to come out? I’ve tried bribing with treats but he doesn’t seem to care.
