If you’re familiar with the technology world, you know that companies like Apple, Microsoft, and Samsung sue and get sued almost everyday.

Oli-Dri now claims that Nestle is infringing on their patent and demands monetary compensation. Nestle denies the charges so the kitty litter battle may have to be settled in court.
