Does anyone know what kills frogs by chewing off all their legs and

them whole. There are no snappers in the ponds because of the nets. What
other than a cat would do this to frogs. We have almost no frogs left
and were once crawling with them.

The smaller 900g pond no longer has a net or fish. It's for lilies and
frogs now... but there are almost no frogs now. :*(

My cat kills frogs in the way described.....usually it is just the guts
left on the doorstep with maybe a leg or two to allow you to identify
the poor victim but not always....he did bring in a grass snake once and
deliver the entire body onto one of the children's beds at lights
out....of course following the screams lights out extended quite a few
hours afterwards that evening.....

Seriously frogs seem to be quite fickle.....my old water
feature/fountain thingy had at least 4 frogs in residence....my
replacement pond only has two at the moment but it is new.....I would
suspect that the changes you have made to the pond have caused the frogs
to decamp for a while - they or their desendants, or new frogs will
probably be back next year if not sooner....they seem to have a great
ability to sniff out water
