Abstract
The addition of urease negative bacteria to sodium smectite clay minerals in pet litter inhibits growth of urease positive bacteria for a period of several days, thereby retarding formation of ammonia and other obnoxious odors. Approximately fifty percent sodium bentonite in the litter causes the litter to clump upon wetting, maintaining the urea in contact with the treated clay and also serving as a buffer to favor growth of the urease negative bacteria.
Claims19
A method of suppressing production of odor from animal wastes in pet litter, comprising:
- first, mixing urease negative bacteria with granular silica;
- and
- second, applying to pet litter an effective amount of the mixed urease negative bacteria and silica.
A method of suppressing production of odor from animal wastes in pet litter, comprising:
- first, providing a culture preparation containing urease negative bacteria, bacterial growth medium and bacterial growth by-products;
- second, mixing said culture preparation with granular silica;
- and
- third, applying to pet litter an effective amount of the mixed culture preparation and silica.
An odor retarding pet litter, comprising:
- an absorbent composition;
- and
- a decomposition retarding urease negative bacteria combined with said absorbent composition in an effective amount to inhibit growth of urease positive bacteria when, in use, the absorbent composition is contacted with animal waste;
- wherein, said urease negative bacteria is carried by a granular silica.
