My rabbits will go a few hours without eating. They do sleep after all. Could he have gas? Have you tried rubbing his tummy?

if it was tooth trouble he would probably not be eating and certainly not gnawing on the bars.

Sounds like it was an isolated event. I’m glad he’s behaving normally now.

The sudden tooth grinding and thumping sounds like something startled or scared him. Porky sometimes at night gets all stiff perks his ears and thumps. We suspect it’s the fox, who we see paw-prints from and my son once found hiding under our porch, passing too close to Porky’s window and making him nervous. He has also thumped and hidden under my lawn chair while outside getting fresh air and exercise b/c an airplane flew over low.

Most of us only check in here once a day, twice if we’re bored. I sometimes go several days or even weeks without checking in if I’m on vacation or things are hectic. Getting responses in less than 20 minutes would just be lucky timing.
