Life Hack: Drains
Any house that has fuzzy creatures needs to have fur trappers on every drain: kitchen sink, bathroom sink, and shower. I am amazed how often I wash an object that has neither horse nor pet contact, only to end up with a stopper full of gunk.
Many years ago, I stayed at a beachhouse that suffered from clogged pipes. I was shown the offending mass of sink, shower, and toilet elements curled in the bottom of a trash can. The clog was the size and shape of a full-grown boa constrictor. Clearly, the sight scarred me for life.
