Has this incident happened to anyone of you guys? it happened few months back. So I realized I might share with you.
I read lots of articles and ebook on how to keep minimum water surface fro the edge of the pond..at least 6 inches. Mine is more than 12 inches BUT she still can jump off the pond. I think this is a rare case. Luckily, at that time I still awake, heard a knocking sound, 5 minutes later I came out, and saw her bleeding,with her mouth searching for someone to give her CPR.huhuhuhu!
For those who wish to build one, this factor matters.
