The registration for RunningCat.com expires in October 2022. The domain was first registered in 2001. I saw this domain become available from an expired domains list and really liked it. I even had business cards (remember what those are?) printed. I never got around to serious site work, though.
What could you do with the Running Cat Domain?
I think this is a “Brandable” domain and will work for someone in a fast-paced business or occupation. Realtor, Stockbroker, etc. seem like they might work.
