I lost a little degu yesterday...she was doing poorly, not eating...and she passed away yesterday. I don't know how old she was, as she came through a rescue, and they had no info on her at all. Her cagemate, Trillian, is still bright and perky, and Quark, who lives next door to their cage is fine also. I'm hoping it was just old age that got her.
RIP Teyla... Poor little Goo Girl.
