Not the best #caturday post but I'm looking for advice from the #cats crew.

The vet has recommended we feed my cats, Oscar and Hank separately. They're refusing to comply. When I shut them in separate rooms with food they each go straight to the door and meow until they can swap. This is regardless of who is being fed in which room. We don't have designated bowls for them so when they switch rooms they switch bowls as well. It is impossible to track how much each cat is actually eating.
