Don’t stop at dogs.. get cats to submit samples too... and squirrels, rabbits, homeless.. ya know.. Diversity yields results, right?
Oh yeah on cats! In the summer I leave my large shed/workshop 2-car door open a lot because I am in and out a lot and to cool it off a bit. The cats climb up onto the plywood floor above the ceiling joists and poop all over the place when I'm not inside. It's disgusting. Also, they poop under an overhanging part on our house. Maybe they are feral, but whose fault is that?
*** Also, how are the poor people going to afford plastic bags to put the poop from their 5 dogs?
