As I mentioned sometimes Mr.Uma haven't seemed well recently, he doesn't eat & poop well, sometimes looks like being sick and I've been worrying about him much. I e-mailed an acquaintance who is also a rabbit-owner and has much knowledge about rabbit, she introduced her vet to me and said he was really good and reliable.
So this morning I got up early, put Mr.Uma in a pet-carry bag, took train then bus to visit the veterinary clinic.
What the new vet found shocked me, one of Mr.Uma's back tooth had grown too long and to the wrong direction so its end stuck into the inside of his cheek, he must have been in pain for a while. I knew it could happen but I had no idea how my vet could overlooked it.
Fortunately this new vet seemed be really good at treating rabbit, he cut the end of the overgrown tooth without anesthesia. He showed me the thing he cut. It was a tiny tiny piece of tooth but hard enough to make pain. We expect that within 2 or 3 days the injury inside of Mr.Uma's mouth would heal and he'd be able to eat many dried timothy grass which is vital for his health.
I feel terribly sorry for having kept him in pain for.. maybe weeks, or months I'm afraid. It's horribly long time for a small animal.
Tonight he still doesn't seem to be in his best condition but lively enough, I hope he'll feel better soon.
