Claim 11
Independent Claim
58 words
A method of delivering an ammonia-controlling effective amount of odor controlling agent to an animal litter comprising: (a) providing an adsorbent or absorbent animal litter; (b) applying to said litter, in a liquid dispersion, a mixture of an ammonia-controlling-effective amount of pine oil and boric acid; the dispersion then carrying said pine oil substantially uniformly over said litter.
Claim 12
Independent Claim
58 words
A method of delivering an ammonia-controlling effective amount of odor controlling agent to an animal litter comprising: (a) providing an adsorbent or absorbent animal litter; (b) applying to said litter, in a liquid dispersion, a mixture of an ammonia-controlling-effective amount of pine oil and boric acid; the dispersion then carrying said pine oil substantially uniformly over said litter.
