Mumbles (Blue Quaker) loves to have the run of the house. And he particularly loves to climb curtains and roost on curtain rods. It makes for the occasional fright as a previously unseen angel dives at a passing stranger... but is also makes for yucky dropping stripes.
The tip is painter's tape. The blue stuff that doesn't stick very well. A couple of well places strips of the tape behind the curtain (where you just wiped the droppings away) will make weekly cleanup a breeze. Clean up is just a peel, toss, and reapply.
Do others have tips on how to make a house fit for a roaming fid?
