I think he just wants a change of diet. He does eat his renal kibble. He loves it a lot. So his morning I just gave him kibble for breakfast which he eats enthusiastically and last night he had kibble as well instead of wet food. He told Fern that he felt some nausea some weeks ago and that may be why he is off his wet food. I decided to give him some probiotics and wheatgrass to settle his stomach but if cos the grass will be here some time later as he only eats grass in trays.
He quite likes this probiotic and eats it without fuss. He gets it twice a day. We will see if he gets better. I don't think it's wrong for him to just eats kibble but as he has kidney issues it's probably better if he eats wet food as well.
