Abstract: An apparatus comprising at least one access controller device 100, comprising: a controller 104 configured to deliver access signals according to an access schedule based on data entered into the controller by an operator; and a movable barrier 108 configured to be positioned in a home cage 102 between a storage area 116 and a living area 114 and configured to be movable between an access position 112 where there is unrestricted access to an item in the food storage area from the living area and a restricted position 110 where the access is denied. The movable barrier is moved between the access position and the restricted position in response to the access signals. The movable barrier is configured to fit entirely within the home cage and a food hopper of the home cage without making any modifications to the home cage or the food hopper.

Abstract: An outdoor bag holder is made up of a rigid bag supporting member ("rbsm") that has a multiple of corners, two legs that are rotateably attached to the back of the rbsm, a U-shaped support arm, and a resting plate. The U-shaped support arm is rotateably attached to two sides of the rbsm. The resting plate is attached between the two legs, at a height such that when the U-shaped arm is supported by the resting plate, the rbsm is held perpendicular to the two legs. The dimensions of rbsm are chosen, such that when a bag of the type and size for which it was designed, has its mouth folded over the rbsm, the bag will be held open, and in place, by the tension between it, and the rbsm. The rods are of a shape and diameter, to allow them to be inserted into the ground, and are long enough, so that they can be inserted sufficiently far into the ground, so that the bag holder is held up, and at the same time, leave sufficient clearance between the rbsm, and the ground, for the bag for which it was designed.
