The plastic bags from the grocery i reuse to bag the cat turds from the litter box.
Haha, I do the same. That and for a trash receptacle in my car. Soon to run out though, with Alaska's recent ban on plastic bags. Now the cardboard grocery bags are repurposed as wood stove firestarter
I have permanent bags, but I am still getting used to this and always forget to bring them in. The untimely death of our species is apparently not enough motivation for my lazy american ass.
