For the last few days, our gerbil Stacy was moving slowly, resting a lot, and just not acting like herself. Yesterday when we got up we discovered she had died during the night. This is our first pet to die and we have all been sad, even though we knew Stacy was getting old and wouldn't live much longer anyway. Our other gerbil, Lily, can tell something is different, even though the two have been in separate cages for a while now because they had started fighting. We will miss Stacy and the little things that gave her a distinct personality. We buried her in the back yard and marked the spot with a rock.
