Pet Waiter Systems is an innovative and useful device for easily and efficiently feeding domesticated pets, such as cats and dogs. The systems may include a pet nourishment station assembly, a container holding member, a tray elevator assembly, and a motor assembly. In use, a nourishment tray may integrally include a stainless steel food bowl and water bowl. The nourishment tray may be easily adjusted vertically via a handy control panel for making it easier on a user to dispense a ration of pet-food and drinking-water into the bowls contained within the nourishment tray which may serve to reduce injury caused from excessive bending.
