I am so sorry Ian. I really wish that there was more we could have done to help. From here we can only advise and try to help diagnose what's wrong. The hurt you feel is perfectly natural when a loved one is lost. These are not just frogs to us. They are friends, they are family members. They were and are loved by us. Don't give up because Kirby is gone because he is not. His memory lives on in you and in his photos. When you are ready you will try again with another frog. It would be best to wait of course. Kirby can't be replaced but atleast there will be another out ther that needs a home and perhaps you will be the one to give the frog a good one. Once again I am so sorry Ian.
