Abstract: A system for detecting protein in mammalian urine is disclosed herein. Phloxine B buffered between pH 2-2.5 undergoes a color change from colorless to red in the presence of protein. Disclosed herein are animal litter compositions and additives comprising Phloxine B and a protein-sequestering agent buffered at a pH below about 3 which detect the presence of protein at levels indicative of ill-health in feline urine.

Abstract: A container is disclosed which can include a container base having a cavity therein, a thermal source disposable in the cavity of the base, an insert being insertable within the cavity of the base such that the insert is in close proximity to the thermal source, and a cover. The cover and the insert can define a sealable compartment for the storage of food items. In other embodiments, the cover can be engageable directly with the base to define a storage compartment. The thermal source can act as either or both a heater and a cooler to help maintain the food items stored in the container at a desired temperature.
