Thank you for your reply- the medication given to him is Onisor, robenacoxib
That sounds like Mordin :) He is a very nervous cat, especially around other humans except myself and my wife, at the vets yesterday he was kept in a carrier for over 2hrs, with some very lively dogs in the waiting room, he wet himself as well which is unheard of for him, I just checked on him under the bath, he does look scared.
He has however been off his food and water. Would this be normal for a little guy in his situation?
After taking him back to the vet, we found it wasn't a sprain, he had infact got an absess, which is now being treated with anti biotics and anti flammitry. He is getting back to himself :)
