Well we went to the white coats on Saturday.
This boy is good as gold. Purring the whole time. Every thing looks good 1/2 deg. up on temp, some ear mites. But the back and leg seem to be fine. We suspect a mussel bruise. Fell or someone jumped on him.
This does not surprise me the he comes down the stairs (I think he tries to out run the 4 legers) or playing in the bath tub.
Got a long lasting pain shot and we will see what happens over the next few days..

Thank you everyone.
