The pet drinking fountain allows pets to have a source of running water whenever they desire, but without having to constantly run the water. The pets can learn to press the frontal pedal of the fountain bowl to open the cover and begin the running water. Then, once the pet has finished drinking, they can release the pedal to stop the water from needlessly running and to shut the cover again for cleanliness. The pet drinking fountain is anchored to the ground to prevent the pet from moving its location. Additionally, it requires a water source and disposal to continue to provide clean water for the pet.

A method and apparatus for dispensing a liquid when licked is disclosed. The apparatus comprises a substantially spherical member; a cap member, and a valve. The cap member comprise a concave member adapted to accept a spherical cap and retaining the spherical member within the concave member while forming a volume therebetween, and a valve, in sealed hydraulic communication with the volume between the spherical member and the concave member, the valve permitting fluid communication between the volume and a vessel sealingly affixed to the cap member in a first configuration and prohibiting fluid communication between the volume and the vessel in a second configuration.

This disclosure provides apparatus and methods for watering livestock using a livestock waterer, a water source, and a waterer valve system for replenishing water in a water reservoir of the livestock waterer. A valve housing can be affixed to the water reservoir and coupled to a plunger. A cam can be pivotably coupled to the valve housing and one end of a float arm. A float component can be coupled to the opposite end of the float arm. Water from the water supply can enter the valve housing and exit an orifice in the valve housing along first and second side spouts. The float component can have a generally flat bottom and move vertically along with the water level within the water reservoir. As the float component moves vertically, the float arm pivots the cam. The cam can move the plunger in the valve housing to stop water flow.

An automatic pet water feeder includes a water replenishing assembly including a bucket body, a bucket cover on a mouth of the bucket body, a silicone plug in the bucket cover, and a movable pin configured to telescopically drive the silicone plug to block and dredge the mouth of the bucket body; and a filter assembly including a shell and a filter element in the shell. One end of the bucket cover is inserted into the shell. The filter element is configured to filter water flowing from the bucket body. The pet water feeder may filter drinking water multiple times through the filter element so that water may be effectively purified. The bucket body may be automatically blocked by gravity through the telescopic movable pin, so that water may not be spilled when being changed.

A cage for housing laboratory animals, said cage includes a bowl and a cap or cover which may be positioned on said bowl in a removable manner, wherein the cap and the bowl, with the cap positioned on the bowl, define an internal space which is closed and not accessible from the outside, wherein in the internal space a feeder is positioned, adapted to contain food adapted to feed the laboratory animals, wherein the cage is equipped with first means adapted to detect the presence and/or quantity of food in the feeder.

A device is provided for studying the ability of at least one mouse to find its bearings in a maze, the device including a plurality of houses distributed around a central agora and in which at least one stimulator allows the at least one mouse to carry out certain activities and/or satisfy certain primary needs. Each house further includes at least one sensor for measuring the activity of the mouse in the house, and more particularly its use of the at least one stimulator. Finally, a sensor makes it possible to detect and measure the movements of each mouse in the device. Quantitative parameters originating from these measurements thus make it possible to highlight the quality of the geographical memory of the at least one mouse.
