I wet Sam's food already, if I don't, he wont eat it.
As PennyB said, I think Sam is not eating his food because he knows there is a bowl of Tuna in the fridge, which we have added to one meal every other day. As long as there is Tuna mixed into his food, he will eat it straight away, but I don't want to use it all the time because then surely he will do the same and stop eating it and look for something else.
I've not tried to lift his bowl after 15 mins becuase sometimes he does have a small bite then leaves it. So I suppose I should let him have a wee nibble and if he doesn't touch it 15 mins later, then lift it? Not really sure what to do here.
I'm just worried that he is not eating enough, although he's not losing any weight.
Denise - I've changed him over to 2 meals and I think this is helping, as seems to be more interested in his food.
I'll give it another few days and try lifting his food after 15 mins and see how we get on.
Thanks everyone for your advice, it's really appreciated!
