A process for making an animal litter from a woody biomass starting material is described, with the performance amendments substantially located entirely on the outside surface of the woody biomass particles. The process may include the steps of densifying the biomass starting material, crumbling the densified biomass material; screening the densified biomass material for size; optionally adding a zeolite containing a scent; spray coating the sized, densified biomass particles with a surface adhesion agent; and powder dosing the sized, densified biomass particles and zeolites with a performance amendment comprising equal parts bentonite and guar gum.

A chromogenic absorbent material for an animal litter includes an oxidizing agent responsive to peroxidatic/pseudoperoxidatic activity in an animal excretion or a first catalytic compound generating the oxidizing agent in situ. The material also includes a chromogenic indicator being chromogenically responsive to the oxidizing activity of the oxidizing agent, and an absorptive material which is porous, for absorbing the animal excretion. The absorptive material includes a water-absorbing polysaccharide providing absorptive properties to the chromogenic absorbent material; and may also include a second polysaccharide and a superabsorbent polymer. The material may be obtained in the form of particles having a low density and a high porosity, and is usable in conjunction with an animal litter for detecting various diseases in animals.

An apparatus according to the present invention provides a multiple piece pet bed having gradual depressions for the resting of body parts, and stackable supporting bed floors. The pet bed includes a supporting bed floor. The pet bed includes a detachable soft cover. The pet bed includes a cloth cover. The detachable soft cover and support bed floor may be preferably configured as polygons. A wall of the stackable supporting bed floor is adapted to engage a channel of a detachable soft cover. The multiple piece pet bed is designed to provide for mobility in use, comfort for the occupants, and cost savings in production.

A pet carrier assembly, including: a cage housing adapted to selectively contain a pet; and a lower litter pan adapted to be selectively coupled to and removed from a bottom portion of the cage housing; wherein bottom portion of the cage housing includes a waste grate that forms at least a portion of a floor of the cage housing and is selectively disposed within or adjacent to an interior portion of the lower litter pan with the bottom portion of the cage housing. The pet carrier assembly includes a solid removable floor disposed in the bottom portion of the cage housing and adapted to cover the waste grate, and a seal disposed about a periphery of the removable floor. Optionally, the lower litter pan includes a cut away operable for providing access to an interior portion of the lower litter pan.

A rack system including a plurality of cages, wherein each cage comprises a respective plurality of outside surfaces, a plurality of housing areas, each housing area corresponding to a respective one cage of the plurality of cages, each housing area comprising a respective plurality of inside surfaces of the rack system and arranged to support at least a portion of one of the respective plurality of outside surfaces of its corresponding one cage, and a plurality of coaxial piezoelectric cables, each coaxial piezoelectric cable corresponding to a respective one cage of the plurality of cages and at least indirectly coupled to its corresponding one cage.

An at least semi-autonomous litter conditioning vehicle has a chassis. A drive system is coupled to the chassis and can move the vehicle along a floor of an animal enclosure. A collection system is coupled to a front portion of the chassis and includes a flailer that can reduce a particle size of the litter as the collection system collects litter from the floor. A conditioning system is coupled along a length of the chassis and includes a drum that can receive the collected litter and can be rotated to tumble the litter. A heating element of the conditioning system can transfer thermal energy to the litter as it is tumbled in the drum. A dispersement system is coupled to a back portion of the chassis. The dispersement system can receive conditioned litter from the conditioning system and can disperse the conditioned litter on the floor behind the vehicle.

Provided is a carrier material and its use in animal litter, where the carrier material exhibits reduced dust formation during handling. The carrier material comprises: bentonite clay; and a dust suppression agent coated on the bentonite clay, wherein the dust suppression agent is one or more alkoxylate materials of formula (I): RO-(AO).sub.2H, wherein R is H, aryl (e.g., phenyl), or linear or branched C.sub.4-C.sub.24 alkyl; AO at each occurrence is independently ethyleneoxy, propyleneoxy, butyleneoxy, or random or block mixtures thereof; and z represents average number of moles of AO and ranges from 1 to 80.

The present invention relates to a multilayer absorbent filtering item comprising: a first layer of a porous activated carbon support disposed on a nonwoven polyester-fibre felt; a second layer, where the surface of the first layer is bonded to a film of polymer and low-foam surfactants (mixture A); and a third layer, where the surface of the second layer is bonded to a film comprising an active ingredient and a low-foam surfactant in an acid aqueous medium (mixture B), the top face of said polymer film being bonded to the active ingredient, and the bottom face thereof adhering to the activated carbon, by means of polar and non-polar interactions. Also disclosed are a method for obtaining the multilayer absorbent filtering item and the use of the multilayer absorbent filtering item.
