Recently changed up cat food to a light diet formula after the vet told me my cats were overweight. This caused GI upset and resultant soft stools. One cat happened to shit on the dining room throw rug and the robovac proceed to march through the site leaving a smeared trail across the entire rug. It also did several turns, smearing it in a nice cross hatch pattern. And the smell was special.
Spent my lunch break cleaning the carpet.
I threw the vac outside and plan to hose the shit out of it, literally, when I get home.
