Our eldest Gerbil, Brain isn't doing so hot today. He was fine yesterday, but this afternoon I noticed he's suddenly disoriented, cold, and lethargic. Over the past 12 hours, he's gotten continually worse.
He brought us a pair of "surprise" litters when the other gerbil we got at the same time (named "Pinky" of course) ended up being a female. After more than a year together, I guess he finally figured out how to reproduce. The mom died shortly after the second litter came out, and he's lasted more than 2 years after that.
He's about 4 or 5 now, so it's probably his time to depart. It's strange how attached we get to our pets. Even the small ones. He'll be missed
