Dang I bet that was one hard loss, Beardie's are so easy to get really attached to. I'm already extremely attached to my Beardie, she even makes me laugh. If you don't mind me asking, how did Spike go downhill?
Well, CoolioTiffany, he just got old and stopped eating or really being active. Old age gets the best of us.
The good thing is he passed of old age rather than something more heartbreaking. Glad to know he was taken care of pretty well if he passed from old age, many people who keep Bearded Dragons don't give a Beardie everything it needs or give it things it doesn't need.
