My poor, sweet sugar glider Morty died last night. He seemed fine yesterday, but today he was just laying at the bottom of his cage holding onto the bars. I picked him up and tried to feed him, but he was very lethargic and didn't want to eat. Emily and I brought him to the vet last night. They put him on oxygen and tried to figure out what was wrong. But about an hour after we got to the vet, he passed away. He was the nicest little guy and we will miss him.
