Obie looks like a cat again instead of a giant ginger slug 
He is so much happier without his thick coat and best of all he is letting me gently groom him. I bought a comb recommended here with has teeth which rotate and don't pull (he HATED the furminator) and his sister likes it too.
We are contemplating getting some proper Oster clippers to see if we can do him ourselves in future as it seems to be the way forward for him.
Meantime you can see he has suffered terribly... not!
(shaved and now shots included!)
