Dinnertime! Myst has to eat regular Science Diet and a little oil now and then. He can have nothing else or he gets sick. Dandelion has to have hairball formula Purina - and some moist canned food now and then. He has had a super severe problem all of his life and this is the only thing that works. Me? I can have anything anytime -- and I usually do. I love it all. Terry calls me the "Universal Cat" because Dandelion and Myst can not be in the same room together and can not eat each other's food, but I can eat anything and get along with anyone.
