1. A device comprising:
- a. a support base;
b. a chamber, located on the support base, wherein the chamber includes;
i. an entry opening so that an animal can enter and exit the chamber,ii. a shield located within and attached to the chamber;
wherein the shield is movably attached to the chamber so that the chamber at least partially rotates around the shield and after rotation of the chamber an internal surface of the chamber is covered, wherein the shield is fixedly attached to a retainer which can rotate within a holder that is immovably nested in a slot of the support base, with the retainer held static by a preloaded biasing member located between the retainer and holder until a tab on the chamber comes into contact with a tab on the retainer thus moving the shield and retainer with the chamber and further loading the biasing member.

9. A device comprising:
-
a. a chamber having an entry opening so that an animal can enter and exit the chamber, b. a support base, located under and supporting the chamber, wherein the support base includes; i. a weight detection sensor, located in the support base and below the chamber, having; 1. an expandable and contractable member generating a force on the support base, 2. a rocker arm, and 3. a force sensitive monitoring device placed between the support base and the rocker arm, wherein the expandable and contractible member generates a force on the rocker arm and the rocker arm translates the force to the force sensitive monitoring device so that the force sensitive monitoring device detects changes in weight of the device and wherein the weight detection sensor continuously, intermittently, or both monitors the weight in the chamber and compares the weight in the chamber to a plurality of previous weight measurements, and when the weight detection sensor measures an increase in weight relative to the plurality of previous weight measurements, and then a subsequent weight measurement drops and/or rises, the sensor senses that the animal has entered and subsequently exited the chamber and a cleaning cycle of the device is triggered. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
