Jerry and I never do, but then again, it's just the two of us.....well, I should say the 5 of us. We can never go in there unaccompanied......one or all of the kits are with us!
Since getting cats, yes I do. But before that, I didn't, as I live alone. If I leave the door open, the cats invariably rush in and risk getting splattered.
I live alone, so sometimes I do and sometimes I don't. The toilet paper is on the back of the door though, so I have to reach around a bit if I leave the door open.
