We finally scrapped* our ratty shag rug in the living room and replaced it with a wool rug that looks (but isn't really) knitted. Oh man, I love this rug.
Of course, we live with someone who's absolutely desperate to crawl, and otherwise rolls around everywhere, and rubs his saliva-wet hands on the wool, attracting fuzzies he then of course licks.
He hasn't coughed up a hairball yet, but this is what our living room looks like now.
I think the alphabet goes very well, don't you? (No, I don't really.)
*ETA: I mean that pretty much literally – we're going to cut that old rug up so the dog can still have some to sleep on. She loves that filthy old thing.
