My rabbit is on penicillin injections every 2 days to help clear up his weepy eye (he's had 4 injections so far) and his droppings have changed to tiny really light brown ones. He also seems to have totally gone off his dry food, but will eat veg and fruit, though I don't give him much of this because he suffers from sticky bottom and it makes him worse. Does anyone know if the change in droppings is quite normal in rabbits on penicillin and if being on it can make them go off their food? I am in the middle of changing his dry food over from Super Rabbit Excel to Bunny Basics T, but he still has a mixture of both in his bowl, so thinking it can't be that he doesn't like the new food cause he could pick out the Excel if he wanted to.
