Paranooid Paula (lol) I am wishing you and Otis the very very best. I am the never rest til I have an answer type. I would go to the specialist if there was ANY indication of a problem at all. I still stare a diggy and get paranoid if he even squeeks. He lets out this awful noise when he yawns and I go flying to him everytime. He looks at me like What the????? Wether it be MVD, a shunt, hypo, gall bladder, or any other problem I just would be a mess not knowing. Thats just me tho Your probably fine with switching the food and watching him closely. Im just a freak tho lol
