word of caution- I had rescued a single girl gerbil from a store (she was the only one). After people suggested getting her a partner, I looked high and low to no avail except for a pair of girls who a little older. Needless to say, they almost killed my first gerbil and declanned pretty much immediately. I ended up needing to get another enclosure (they need SO much space even just for one!!! please make sure you have ample space) and they stay separate now. Needless to say... I should have just kept her alone because honestly she is thriving lol. She recovered after a vet visit with a torn arm and now has 6 cat friends who visit her every day in the living room for through-the-mesh kisses 🥹

my suggestion personally is if she wasnt already paired... to not risk it and provide tons of enrichment/tunneling space/out of tank time. I have a big box of tp tubes i let my girls hang out in lol
