Noki has been eating Scooters left over wet food and we think he's allergic to something in it. He's licking the hair off his butt so he has to wear the donut. We know he's allergic to wheat but neither his dry food or Scooters wet food has any so we're guessing he's also allergic to the soy in the wet food. Trying to keep him from eating the leftovers and also switching it up with a different brand.
Now this is an Elizabethan collar I can appreciate, very dapper.
(Get well soon!)
