The herein described Stock Tank Guard is generally comprised of a hanging guard structure situated over an existing livestock water tank. The hanging guard structure is preferably constructed of a plurality of interchangeable members, which can be configured in any shape or size to fit over any existing livestock water tank. The guard structure hangs from a plurality of support poles fixed along the exterior perimeter of the existing livestock water tank. In an alternative embodiment, the guard structure hangs from a frame system comprised of interchangeable members erected around and above the existing livestock tank. The interchangeable member feature of the described invention has the added advantage of being able to package, sell, transport, and erect the apparatus in remote locations without heavy equipment that would be necessary for fixing large steel posts in the ground.

A pet drinking device includes a water tank including a water storage chamber for storing water and a drinking water trough for pets to drink water; a circuit board arranged on the water tank; a water pumping mechanism electrically connected to the circuit board, the water pumping mechanism arranged in the water storage chamber and configured to circulate water in the water storage chamber and the drinking water trough when the circuit board is driven; and a filter element assembly. The filter element assembly includes a softened water quality filter element for softening water quality, a heavy metal filter element for filtering heavy metals and an antibacterial and deodorizing filter element for removing peculiar smell, the softened water quality filter element, the heavy metal filter element and the antibacterial and deodorizing filter element are arranged on the water tank for filtering water during water circulation.

A method for monitoring an animal's consumption of material includes sensing an amount of material that is held in a container and that is to be consumed by an animal, and comparing the sensed amount with an amount of material that was previously sensed in the container. Then, in response to the sensed amount of material being less than the previously sensed amount of material, the method also includes determining whether the animal consumed the removed material. In response to the animal consuming the removed material, the method then includes calculating the amount of material consumed by the animal, recording the amount of material consumed by the animal, and establishing the sensed amount of material as the amount of material previously-sensed for use in a future comparison of a subsequent execution of the method.

An ozone pet water dispenser including a main body, a control host, a pump body, a heating unit, and a hydrolytic ozone generator. The main body is formed with a storage chamber, a drinking trough, and a water return port respectively communicating with both the drinking trough and the storage chamber. The control host includes a housing mounted on the main body, a first circuit board and a switch unit disposed on the housing, with the switch unit electrically connected to the first circuit board. The pump body, electrically connected to the first circuit board, is activated by the first circuit board to pump water from the storage chamber to the drinking trough. Both the heating unit and hydrolytic ozone generator are electrically connected to the first circuit board.

A heater for a hummingbird feeder includes a waterproof heating pad with an adhesive surface for attachment to the bottom of a hummingbird feeder, and a power supply system comprising a weather-resistant transformer and power cable. The power cable may be permanently attached to the heating pad or detachably connected via weather-resistant electrical connectors. The heating pad generates thermal energy to prevent nectar from freezing, allowing hummingbirds to feed in cold weather conditions. The compact, universal design fits any hummingbird feeder model and requires no tools for installation.
