This particular House of Mews started out with a pun. The three members of the household had just recently gotten acquainted with several talented ficwriters/artists/creative sorts, and we wanted to create a collective household journal back on pitas.com. We were joking around about being muses, when suddenly that combined in unholy fusion with our collection of household cats and became "Mewses."
And it stuck. For a while we maintained a PITAs blog called House of Mews, which is still out there even though it hasn't been updated in a long while. (At the time, we had not yet heard of the better-known "House of Mews" - a feline rescue society out Tennessee way.) As Livejournal became more popular, we eventually followed our friends to here.
