I'm sorry to hear about your frog. I know how you feel as far as having one die unexpectedly. When mine died, I instantly thought it was something that I may have done or something. But I also have to keep in mind that some things are or were meant to be, however I still wrack my brain as to what happened.

Don't beat yourself up about it, just try to keep all your other frogs as happy as you can. That's all you really can do.

Again, sorry for your loss.
