Cena is the minimalist in the feeder lineup. Filip gordon frank drew it as a single continuous contour of thin powder-coated metal, a line that seems to hold the bowls in mid-air. The slight lift makes eating more comfortable for your cat while keeping the whole object almost weightless to the eye.A silicone ring settles each stainless bowl so it will not rattle, and four small feet keep the frame from skating across a smooth floor. The bowls lift out for the dishwasher and can be bought on their own.
