cat supplies (Rockville)

Hello! I’m in the Aspen Hill area and recently got a new cat. I’m looking for any cat supplies someone no longer needs and wouldn’t mind giving away. Things like a litter box, scoop, toys, a scratching post, a carrier, or really anything else for a cat. I use public transportation, so something in the Aspen Hill or Rockville area would be easiest for me to pick up. Thank you!
