my 4months old male Lionhead bunny seems to afraid of anything. He was take care by me since he was 1month. Recently, I went on a 2 week trip and left him with my friend who has a dog. I told my friend not to let him outside of his cage but she didn't listen and let him out together with her dog. Now, I got him back home,he got scare of any sounds or any movements I made,and he doesn't remember me at all. He eats and poo well.I found out that he groom himself a lot than normal and just lay down in his cage, not active like before anymore.He forgot the tricks, litter training and everything.
