A connecting ring for coupling small animal habitat parts. The connecting ring can include a hoop, upper tabs projecting from an upper surface of the hoop, and lower tabs projecting from a lower surface of the hoop. The lower surface of the hoop is opposing the upper surface. Each of the upper tabs can include: a respective inner bump extending radially inward toward an interior of the hoop, and a respective inner groove formed between a respective lower surface of the respective inner bump and the upper surface of the hoop. Each of the lower tabs can include a respective outer bump extending radially outward away from the interior of the hoop, and a respective outer groove formed between a respective upper surface of the respective outer bump and the lower surface of the hoop. Other embodiments are disclosed.

A collapsible pet crate is provided that includes a top; a bottom base; and a plurality of walls including a first wall pair. The first wall pair includes a first wall pivotably connected to the bottom base for pivoting about a first horizontal axis and a second wall pivotably connected to the first wall for pivoting about a first vertical axis. The collapsible pet crate being configured for arrangement in a crating orientation in which the top is removably connected to at least one of the walls and a collapsed orientation in which the top is removably connected to the bottom base. A method of providing a collapsible pet crate is also provided.

Systems and method for optical imaging of an animal include a body conforming animal mold, which is shaped and sized to hold an animal in an immobilized and geometrically defined position and a gantry, which can include multiple optical mirrors to provide for simultaneous imaging of multiple different views of an animal within a body conforming animal mold.

A method of training a rodent to identify pairs of same or different odors, whereby the rodent learns the rule irrespective of the particular odors. Once trained, the rodent can be used to measure perceptual odor similarities between members of pairs of odors, which odors may be unrelated to the odors the rodent was trained on.

A washing machine, which is adapted for cages and accessories used in the field of research on laboratory animals, and which has a wash chamber and an assembly for introducing washing liquid and rinsing liquid into the wash chamber, includes: two loading levels in the wash chamber, each loading level having two shelves arranged in symmetrical positions relative to the median longitudinal axis of the wash chamber; supports for the shelves, the supports being located in symmetrical positions on both sidewalls of the wash chamber and allowing the shelves to be arranged at different tilting angles; three washing and rinsing assemblies oscillating and rotating about a respective longitudinal axis in the wash chamber, the three assemblies being fed by the assembly for introducing washing liquid and rinsing liquid, and being interposed between the loading levels and lying in a symmetrical vertical plane in the wash chamber; an assembly for causing the oscillation and rotation of the three washing and rinsing assemblies.

An animal cage heating system includes a support structure for support animal cages and a plurality of thermal elements. Each thermal element is configured to provide localized temperature adjustment to one of the animal cages, and each thermal element adjusts the temperature of an animal cage independent of temperature adjustment provided to other animal cages.

A kit for building a module for a pet comprises two bases and at least three wall panels. Each base comprises a base body extending along a first plane, a base contour wall extending substantially perpendicular to the first plane along its contour and a base secondary wall extending substantially parallel to the base contour wall thereby defining an anchoring space therebetween. Each wall panel comprises a panel body and a panel secondary wall substantially parallel to the panel body for insertion into the anchoring space between the base secondary wall and the base contour wall.

The invention relates to an apparatus for charging a remote feedable circuit bioelectronic implanted in a patient or in a laboratory animal, said apparatus comprising a composable container configured to define a closed environment suitable to receive a patient or a laboratory animal, said container comprising a plurality of composable walls made of a nonmagnetic material and connected to each other so as to define said closed environment, said container comprising at least one first winding whose axis is arranged in a first direction (Z) and at least one second winding whose axis is arranged in a second direction (Y) perpendicular to said first direction (Z). The apparatus further comprises a system for powering and driving the windings of the composable container, said system comprising a switching power driver for each winding, a plurality of phase locked loop circuits respectively connected to each switching power driver and connected to a programmable logic circuit of the powering and driving system, said programmable logic circuit being configured to perform a phase comparison, the programmable logic circuit being in turn connected to a microprocessor of the powering and driving system, said microprocessor being configured to provide driving signals to the windings for generating inside the container a rotating magnetic field.

A portable inflatable pet nest includes an airbag, forming a pet nest after inflation, an interior of the pet nest is provided with a cavity, an out wall of the airbag is provided with an exit and entrance communicating with the cavity, and charging and discharging interfaces. In being used, an air pump is connected with the charging and discharging interfaces and inflates to the airbag, the airbag forms the pet nest after it is inflated, the cavity in the pet nest can be used for the pet to rest. When not be used, the charging and discharging interfaces are opened, the air in the airbag is released so that the airbag can be folded. The portable inflatable pet nest occupies a small space, it is convenient to store and transport, and the transportation cost is greatly reduced.
