ok latest update... lui is been much better today only yelping every now and then! nicky 12 thanks for your comments .. it sounds like he may not have this as he is eating, drinking, playing etc. but when he yelps he goes stiff. Really not sure what it is. It's almost like spazems but vet said it could be a number of things. cant get to vet till snow clears as both mine and my bfs cars are stuck in snow and wont move. Lui has been on metacam for 48 hours nearly. x
