He meows in the litter box :-\
Not sure why, he doesn't seem to have constipation or anything... his food has fiber in it also, from psyllium, and not too much of it either, which can also be bad... but ever since day one, he meows when he's defecating in the litter box... Not only during, but also right before, when he's making the hole in the litter... I'm worried -- tomorrow's his first vet. visit, so I'll ask then, but I'm not sure what they'll recommend since most frown upon raw diets. Any ideas?
