Does anyone have any suggestions. I had two rabbits and one got head tilt and was so unwell I had to have him out to sleep as he was in pain. My other rabbit is clearly confused but is now biting me whenever I get him out, not so much once he's out but during getting him out and putting him back. I know I need to find him a friend but how soon do you do that, he's only 10 months so can I get a baby and slowly introduce them or do I see if I can find an older bunny???
