Ok, so the raw thing has been going great until about 3 days ago. He has just been nibbling on his meat for this time. Well, today he did not even touch his meat at all the whole day. We gave him fresh meat twice today and he never even nibbled. I got scared b/c he had not ate all day and gave him some wet food. He took about two bites of it and then just left it. He is not crying or anything. Is it posssible that he is just not hungry? I just don't want him to get sick from not eating. What should I do???
