We knew that B's favorite guinea pig was nearing the end of her life. She held her one last time before she went to bed and cried for a while. The next morning, she was still alive when we got up, but later in the day when we returned from an outing, she was gone. B grieved for 2-3 days but has gotten a little better each day. It has helped that we've had a lot going on to distract her.
Goodbye, sweet Rose! You were a great pet!
