A health monitoring system for caged birds is described. An enclosure containing sensors and associated circuitry mounts to the outside of a bird cage with a perch protruding into the cage.

The sensors included in the present embodiment are a strain gauge load cell for bird weight measuring, a temperature sensor, and an ambient light sensor. The load cell is used with a perch such that the bird's weight can be measured whenever they alight upon the perch. Also included is a piezoelectric sensor to measure vibration data from the cage itself, which is used as a proxy for the bird's activity level. Associated circuitry and software processes and transmits this data to an internet-hosted server. The user can access this information to track a caged bird's weight, activity level, and environmental conditions over time.

A sliding door for a metal wired pet cage includes a pair of torsional springs; a rotary locking member; a rotary lifting handle; and a sliding-type door plate; wherein sliding guide rails of the sliding door are configured longitudinally, wherein the lifting handle is hingedly fixed to an upper end of the sliding-type door plate, the pair of torsional springs are fixed on the metal wired pet cage and are connected with both ends of the locking member, and the torsional springs is configured to drive the locking member to prop against the lifting handle so that the sliding-type door plate is at a locking state. When the sliding type door plate needs to be opened, the lifting handle is rotated upwards so that the locking member is separated from the lifting handle, and the lifting handle drives the sliding-type door plate to move upwards along the sliding guide rails.

A multiple animal cage system is a two tiered animal cage adapted to house at least one animal in each cage. The cages are designed so that animals of different species or animals of the same species can be caged. The cage has an upper cage portion and a lower cage portion and each cage portion has a front access door and a slide-out tray in the bottom that catches animal droppings. The cage is mounted onto wheels for easy portability.

A display apparatus includes a transparent electronic display such as a non-backlit LCD screen, a display area disposed behind the transparent electronic display, and a light source for illuminating the display area. When the light source is activated, the pixels of the LCD screen, and objects behind the screen, become visible. Various examples of the display apparatus include additional enhancements to the visual image and/or functionality. These enhancements include additional monitors for coordinated displays, user-controlled turntables with coordinated informational displays, parallax compensation, RFID sensors for identifying objects to be displayed, and switchable liquid crystal films and/or polarized mirror coatings to further control revealing and concealing of objects behind the screen. Some examples of the display apparatus may include an animal habitat. The animal habitat may be selectively revealed or concealed. The display apparatus may incorporate screen displays with animal movements for unique visual effects.
