A bowl assembly having a bowl and a fill cup. The bowl is configured to be supported on a barrier at a first barrier side. The fill cup is configured to be supported on the barrier at a second barrier side that is opposite to the first barrier side. The fill cup and the bowl being capable of being connected together through an opening in the barrier.

An animal cage includes a removable, suspended interior floor provided with a plurality of perforations formed therein. The floor creates a plenum inside the cage allowing air to flow laminarly through the perforations and liquids or liquid waste to substantially fall through the perforations in the raised floor.

The testing chamber for laboratory animals includes multiple testing points to provide multiple tests and testing zones within the same chamber. The testing chamber for laboratory animals provides for study, testing and assessment of cognitive and motor skills of laboratory test subjects, such as mice, rats and the like. The multiple tests performed within the testing chamber may be used for an overall characterization of the neurobehavioral activities of the test animals. The testing chamber for laboratory animals includes a housing divided into first and second zones. A beam for balance beam-style travel from the first zone to the second zone is provided. A volume of water may be contained in the first zone, and the second zone may contain platforms and ramps for the laboratory animal to travel over. A passage from the first zone to the second zone may be further provided.

A system includes a wall mount adaptor that may be configured to be secured to a wall. The wall mount adaptor may have a top recessed portion disposed proximate the wall and a plurality of slots disposed on a side of the adaptor opposite the wall. A cover or back splash may include a mating adaptor having a protrusion that may extend along a wall facing side of the mating adaptor and be configured to be received by or engage with the top recess. The mating adaptor may also include a plurality of connectors or pins that extend from the wall facing side, each of the plurality of connectors or pins may be configured to be received by or engage with a respective slot.
