A pet feeding system can include a housing, a food tray connected to the housing, and a liquid tray connected to the housing. The pet feeding system can include a food dispenser connected to the housing and configured to dispense food into the food tray. The pet feeding system can include a liquid dispenser connected to the housing and configured to dispense liquid into the liquid tray. The pet feeding system can include a controller communicatively connected to the food dispenser and the liquid dispenser. The controller can operate the food dispenser to dispense the food into the food tray and can operate the liquid dispenser to dispense liquid into the liquid tray.

A pet house includes a bed base, a heat-conducting cover plate covered on the bed base, an electrical appliance cavity being formed between the bed base and the heat-conducting cover plate, a heat dissipation component fixed in the electrical appliance cavity, and a semiconductor refrigeration sheet one end of which cooperates with the heat dissipation component for heat transfer are fixed in the electrical appliance cavity, the other end of the semiconductor refrigeration sheet is in contact with the inner wall of the heat-conducting cover plate, and a lying pad for the pet to lie on is arranged directly above the heat-conducting cover plate. The semiconductor refrigeration sheet is electrified to enable the corresponding end face of the semiconductor refrigeration sheet which is jointed with the heat-conducting cover plate to refrigerate or heat, and the heat is transferred outwards to the lying pad by the heat-conducting cover plate.

In one or more arrangements, a failure indication system is provided having a light assembly, a heating mat assembly and a control circuit. The light assembly is configured to project a wavelength of light that is visible to animals and that illuminates the heating mat assembly to attract an animal to the heating mat. The control circuit is configured to detect when a fault has occurred with the heating mat assembly. When the control circuit detects that a fault has occurred with the heating mat assembly, the control circuit causes the light assembly to indicate the heating mat assembly is not functioning properly.
