Abstract
The present invention relates to an animal litter comprising a carrier material of calcium silicate, which is at least coated with sodium-containing bentonite, the animal litter comprising a complexing agent for complexing free calcium ions and/or a component forming poorly soluble salts with calcium ions, and to a process for preparing it.
Claims8
Animal litter comprising a carrier material of calcium silicate, which is coated with sodium-containing bentonite characterised in that the animal litter comprises a complexing agent for complexing free calcium ions and/or a component forming poorly soluble salts with calcium ions.
The animal litter as claimed in any of the preceding claims, characterised in that the complexing agent or component is selected from the group consisting of ethylene diamine tetra-acetic acid, sodium sulphate, sodium phosphates and potassium phosphates.
The animal litter as claimed in any of the preceding claims, characterised in that the complexing agent and/or component is provided between the carrier material and the bentonite coating as a barrier layer for calcium ions and/or is mixed into the carrier material.
A process for preparing animal litter, comprising the steps of:
- mixing moistened calcium silicate with sodium-containing bentonite,
- adding a complexing agent to complex calcium ions and/or a component for forming a poorly soluble salt with calcium ions before and/or during mixing,
- drying the mixture obtained.
