Well we have been to the vet and Charlie was wonderful, not at all stressed in the basket and almost fell asleep on the scales in the surgery. Vet said there is really no reason why he should be shaking his head etc so has given him a new steroid which does not have the side effects of prednisolone, just the anti inflammatory and I have to call him in a week to let him know how Charlie is doing.
Discussed his behaviour which Kobis (vet) says he thinks is just a part of Charlie's personality. He says I am doing everything I can, Zylkene, Feliway etc but may just have to accept it.
Couldn't find the lump! Have felt it a few times though. Kobis asked where it was and when I showed him said he doesn't think it will be anything to worry about as it is exactly where he would expect a fatty lump to be. Just keep an eye on it.
I am hoping (as, no doubt, is Charlie) that we don't need another vet visit now until his boosters are due in February. Fingers, toes, eyes and paws firmly crossed on that one.
