My rabbits seem to be crepuscular, most active at dawn and dusk, but
they will happily eat whenever there is food in front of them.
I usually feed them in the late afternoon, but I try to keep hay for nibbling available all the time..
There was was an incident I was reading about last year...It involved someone having a problem with an animal control officer who was upset that her rabbits still had empty dishes when it was almost noon.
(I guess for morning people, that is really late in the day.)
It was alarming to me, because I'm a late starter myself. Not usually up until afternoon, because I work nights. I have never had to deal with animal control, but if I ever do, I sure hope that having hay available 24-7 is good enough.
