Questionmy rabbit is not really moving as if his legs cant hold him up. I think it's due to cold weather(i live in New York) but i really don't know???
AnswerDear Satin,
If a rabbit is unable to stand from the cold, then he is close to freezing to death. So this is not likely. It is more probable that your bunny is suffering from hind limb paresis (if this problem is restricted to his hind legs), or to something much more serious (systemic problems, if it's all four legs). In either case, he needs to be taken to a good rabbit vet at once, and you can find one with the list linked here:

I hope this helps.
