Rabbits are as a rule not very active during daytime. They are a crepuscular species, meaning they’re most active in the mornings and evenings. New things and rearranging furniture does stimulate them, because they have lots of curiosity. But when a place has been checked out and cleared as “safe” they are often very content just lounging all day long. They often prefer to be in the same room as their humans though, because to a prey animal, there’s safety in numbers even when you don’t interact directly and actively.
Just to give an example: It’s not good to house a guinea pig and a rabbit together, for several reasons, one of them being because the guniea pig wants to be active during the day and the bunny needs to rest during the day.
Weird though that Bandit didn’t appreciate his tunnel =/ He might get interested in it at a later date, seing that tunnels are very species appropriate for rabbits..
