The Passing of Shadow and Ginger

The kids went in to check on the gerbils today, and they found Ginger and Shadow had passed away into little furball heaven. They have been very upset. This is the first real pet that they've ever had that died. We got the gerbils several years ago, and they only live for 2-3 years. They were going on four years old. The kids didn't play with them much in the past months since we got the dog, and I think they felt guilty about it, but they did keep them fed and they always had water (though sometimes I had to remind them). Now I have two dead gerbils to get rid of (bury) and I have no clue how I'm gonna be able to do that! We live in apartments and don't own land so that's kinda problematic. It is a sad day.
