I bought some of this the other day and have given Sam a very small quantity with a view to gradually changing his feeding. He has been really yucky ever since. He has been sick and is slow and lethargic and is hardly moving about at all. I am taking him to the vet tonight but wondered if the change of food could be a factor and if they ever go off colour when their food is changed. I have not given him any since yesterday and he has had nothing to eat at all today. Any advice would be greatly received as my appointment with the vet is after 5 and I am very worried at th emoment.
Thanks
