Has he pooped recently? Was it of normal appearance?
Did she change brand/flavour of food recently?
Has she tried tempting him to eat? Cheese, people food ie chicken, deli meat, cheerios, catnip, a wee dab of butter, a different cat food
Any manufacturer changes to the smell/texture/consistency of the food he's eating?
Avoid biting when a simple growl will do
