Thanks guys

food does come from the refrigerator so will start waiting a bit before feeding also he does wolf it down as fast as he can manage lol so will also buy one of those anti-gulp bowls and see what happens

I'm changing his food at the moment too as he was on pedigree before which I think is a rubbish food! if it doesn't stop I will go to the vet! I've just been reading more and someone said it can be the liver however I'm not going to jump to conclusions because I've done that with everything so far thinking the worse from reading online then it turns out to be nothing! Lol but will try both those things this week and see if either makes a difference, if not back to the vet, she must love me haha
