Speaking of critters falling into ponds....I believe that, whilst it doesn't get much publicity, a huge number of pet dogs drown each year in private swimming pools - an order of magnitude more than the chidren that do.

A 3 year old girl drowned in the family pool in Brisbane this week - very sad. Didn't find her for 24 hours, until the 3rd time they checked the pool (winter here so not in use)
