Back to the vets tomorrow

I'm taking Grey back into the vets tomorrow. he may have to stay in and have xrays again. This is just so shitty and depressing for him. He's generally more insecure now while he's ill. I don't think he's feeling too happy in himself today. He stood and had a howl when some unusual noises came on the radio and growled at a sock on the floor that he'd left there earlier. His limp is worse today and I just hope we can find what is wrong with him.
