I have a rabbit who is at least 3 years old, he has always been very energetic and spunky. For the past week has not been urinating or pooping very much and has pretty much stayed in his cage. Which is very unlike him. For the past few days he hasn't been drinking at all and was eating almost nothing. Also, he seemed to be in paiin and almost hard on one side of him. And when I would try to pick him up to get him to go to his food, he acted as if I was a stranger and made a noise he's never made before. He also jumped at me as if to hurt me. He's not doing that anymore although it seems as if he has no energy. When I tried to give him water with a dropper he wouldn't open his mouth. I gently pushed the dropper in his mouth and he just let the water fill upand drip out of his mouth until I finally got his tongue and he moved his tongue but it did not seem as if he had swallowed it. When he was in his cage up until 2 days ago he seemed to be so weak he could not get out to eat or go to the bathroom. What could be going on? What can I do to make him better? please help..
