Otis, the last living of our four rat brothers, passed away this morning. This is the first time in nearly 7 years that we've had no pet rats living with us. We've had as many as seven before. We aren't planning on getting any more for a while, either. Probably not until the kids are a little older and able to do the cage cleanup on their own. (We have a HUGE cage.)
Otis had been alone since shortly after Thanksgiving, and I think it was mostly sadness and loneliness that hastened his passing, rather than illness. Poor guy just missed his brothers so much.
Rest in peace, little ratties.
