Abstract
Abstract An animal litter, in particular for cats, is in the form of granulated solid material having a large grain size. The material is expanded and has a specific weight value between 50 grams/liter and 200 grams/liter. In an example, the material is constituted by mica phlogophite in the form of flake treated exfoliation.
