my rabbits legs wont move

Question
I dont know whats wrong my rabbit fell and we didnt notice the we brought him out to play and he wouldnt move a all but he useally moves at the fright of anything i think he paralyzed

Answer
He may be paralyzed due to back injury. If it is just muscular, it can heal. If it is spinal, it is unlikely that he will ever walk properly again. He needs to see a vet to assess the damage and see what can be done. Even if he is paralyzed, depending on the severity of it, he can live a good life. He will need more care, and you can get him a wheelie cart to allow him to move around (sort of like a wheelchair for rabbits).
