Description: a large piece of sponge, but of much greater length and width than depth, e.g. 20″ by 14″ by 2″ (
Manner and process of making: the same as for a typical bath sponge, adjusting for the dimensions.
Manner of using: as with any cat litter mat, place next to exit from litter box. As a cat leaves the litter box, it makes a few steps on the litter mat, so any litter still sticking to the cat's feet gets captured by the mat. The mat can be periodically cleaned by either shaking out the captured litter (e.g., back into the litter box), or using a vacuum cleaner. The mat can also be hand- or machine-washed, then air- or machine-dried.
Best mode of carrying out: as above.
