A device for feeding fish, especially pet fish, according to which a floating body for floating on the water in an aquarium carries tubular means which are inclined or arranged vertically upwardly from the floating body and are adapted to slideably receive and guide fish food bodies arranged one on top of the other. The lower end of the tubular means is partially open to permit fish access to the respective lowermost body of fish food in the tubular means while preventing a dropping-out of the f...

An electronic lock and key system is provided for controlling access. A passive key provides selective access without having a self contained power source. In a passive transponder arrangement, a passive electronic key processes induced or radiated electronic signals to generate a transponder signal for controlling access.

A hanging birdhouse having an aerodynamic asymmetrical teardrop shape. The birdhouse is turned by the wind so that the entry hole always faces the downwind direction. Ventilation slots are provided adjacent to the entry hole so that the wind produces forced ventilation of the birdhouse.

A method for feeding fish raised in a pisciculture environment wherein fish feed is conducted to the fish pen or enclosure carried by a stream of water. To give the feed increased buoyancy after it is introduced into the enclosure, the stream of water is oversaturated with gas, such that gas bubbles penetrate into and/or adhere to the fish feed.

A method and device for feeding animals, particularly fish, comprise supply of food into a conduit (3) by a food supply member (2). The food is transported in the conduit to feed locations (5) by a fluid flow. The food supply member comprises a rotor having cells adapted to be successively filled and brought into communication with the conduit (3) to be successively evacuated by the flow of fluid maintained in the conduit on rotation of the rotor.

There is disclosed an animal feeding system which comprises a means for collecting and storing information regarding an animal's individual characteristics such as milk production or weight, a means for storing information regarding the desired or predicted animal characteristics, means for comparing the desired or predicted characteristics and the individual characteristics and determining the degree of variance between the two, and means for feeding the animal based upon the variance, includin...

An arrangement is provided for controlling animals on a selective basis such as for feeding, watering, and for providing access to controlled areas. A sensor arrangement selectively identifies particular animals, a signal processor processes sensed signals to generate output signals, and an output arrangement provides the control for such animals. In a preferred embodiment, a cat feeding arrangement is provided to permit a pet cat to eat from a controlled food dispenser and to preclude other cat...

A device for holding a hard, molded food item for caged small animals, constructed from sheet metal, including a holder portion formed with a plurality of openings for providing access to the food and a hanger member connected to the holder and provided with means for attachment to a cage. The holder is formed with a top loading opening. The hanger is formed with means for supporting and holding the ends of the holder together.

A method and apparatus for providing special food to a selected plurality of animals in a herd which includes providing a distinguishing device on each of said selected plurality of the animals, and providing a supply of foodstuff in an enclosure having a movable barrier which in a position of rest prevents access to that foodstuff supply and is locked in the rest position by a releaseable lock device. The device is so controlled that the barrier is released for animal access to the food only in...

A structure suitable for use as a bird house, bird feeder, pet house or children's play house made up of long flitches that define both sides and ends of an enclosure. The ends of the long flitches of each side overlying the ends of the long flitches in each adjacent side defining short flitches are disposed in the spaces between the long flitches. A rod extending through the ends of the long flitches in each said corner and through a top supported over said enclosure and bottom of the enclosure...
