I‘m worried that this could be serious since ive read that medical problems in rabbits are pretty hard to spot behavior wise. I dont think hes been acting too differently, but he does eat about half of the food he should (going off his breed’s average weight and the food bag). Im not able to see a vet anytime soon so i dont know what i would do if this turned out to be serious. If it helps, hes a 2 yr old new zealand rabbit we adopted
