Abstract
A composition and method of absorbing animal dross. In one embodiment, the composition comprises discrete particles (about 50 microns to about 3350 microns, preferably about 600 microns to about 3350 microns in size) of a non-compacted water-swellable bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a sufficiently large and stable mass, thereby permitting physical separation of the soiled and wetted water-swellable bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay even after partial drying of about 1 to about 24 hours at room temperature, without substantial sticking to animal paws and fur. In another embodiment, the composition comprises discrete particles of a combination of non-compacted water-swellable sodium bentonite clay and calcium bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a water-dispersible but physically stable mass, thereby permitting physical separation of the soiled and wetted bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay, and has sufficient water-dispersibilit…
