Hard decision...

These few days zizi is behaving differently. I think he's sick. he refuse to eat.. whenever i pass by him to grab my towel.. he will stood in front of his cage and look at me. When i feed him his favorite treats.. he refused. Is he really very sick?? When i talked to husband about zizi he said... "maybe it's time to give him away" I was stunt! speechless.. It's painful. I think before it's too late.. It will be best for me to him more attention. Even tho chinchilla dun really need attention, but i believe he's depriving fer some. Im still in dilemma.... should i give him away?
