The present invention provides recombinant expression constructs comprising nucleic acid encoding mammalian melanocortin receptors, and mammalian cells into which said recombinant expression constructs have been introduced that express functional mammalian melanocortin receptors. The invention provides a panel of such transformed mammalian cells expressing melanocortin receptors for screening compounds for receptor agonist and antagonist activity. The invention also provides methods for using such panels of melanocortin receptor-expressing mammalian cells to specifically-detect and identify agonists and antagonists for each melanocortin receptor, as well as patterns of agonist and antagonist activity of said compounds for the class of melanocortin receptors. Such screening methods provide a means for identifying compounds with patterns of melanocortin agonist and antagonist activity which is associated with the capacity to influence or modify metabolism and behavior, particularly feeding behavior.

A pet food bowl is provided with an integral protrusion that helps to prevent inadvertent aspiration of food by the animal. Particularly for dogs, some feeding behaviors are characterized by swallowing large amounts of food. The protrusion in the bowl separates the food into a peripheral channel within the bowl, and the dog therefore cannot simultaneously secure large amounts of food into its mouth. The protrusion is centrally oriented and extends from the base of the bowl, thereby causing the food to be uniformly distributed within the channel.
