An animal litter is provided for simultaneously delivering urine-absorbent and mental-stimulating properties of the litter. The litter includes in combination a plurality of urine-absorbent particles forming a litter particulate component and a plurality of unfoldable polymeric cylinders constituting a polymeric cylinder component and intermixed with the urine-absorbent particles. The polymeric cylinders have a mean cylinder height of between 1 and 30 millimeters, a ratio of cylinder height to cylinder diameter of 1:1 to 12:1, and a strip length to cylinder height ratio of greater than 10:1. The litter particulate component is present relative to the cylinders in a volume ratio of 1:1 to 25:1. A process is further provided to mental stimulation and boredom reduction of a caged animal. The process includes providing the animal with the above inventive litter and allowing sufficient time for the animal to unfold a portion of the polymeric cylinders.
