I like the contrast in your coat colors, precious Kahlua & Bailey! Decades ago I had 2 gerbils but back then the magnetic wheel wasn't yet invented . . . very clever in order to free up more cage space for tunneling and shredding cardboard. I remember hearing that gerbil tails can come off, yet I think they will regenerate tails, yes? I hope you both have a splendid POTD celebration with your devoted guardians, and get to munch on some sunflower seeds!
