An animal feeding apparatus is related, including a base and a reservoir connected to the base, the medium in the reservoir is driven into or out of the reservoir through a port of the reservoir. The base includes a first cavity communicating with the reservoir, and a second cavity adjacent to and communicating with the first cavity. A piston is movable positioned in the first cavity, and having a first force end away from the reservoir. An activator is movable positioned in the second cavity, and having a second force end away from the reservoir. An linkage member is formed between the first cavity and the second cavity, and engages with the piston and the activator and guide the piston and the activator to move in two opposite directions to get the medium to move into or out of the reservoir. An animal feeding method is also related.

Some embodiments of an inhalation exposure system can deliver a gas, such as an aerosol, to a set of exposure chambers in a controlled manner and can monitor one or more characteristics of the gas at a variety of aerosol delivery rates for output to a user interface. In some implementations, the improved user interface of the system may alert the user to a fitting range of aerosol delivery rates.
