Our cats just kill and leave them by the pond the only thing they have
been
proud enough to bring us was a very cross grass snake :~) why we get so
many
of those in the middle of a village only they know, but they are the chief
predators of the poor frogs often see them in summer disappearing with a
frog in their mouths (everything seems to eat frogs, even the buzzards)
My suggestion to the original poster is don't put expensive fish in your
pond, then you can relax and let nature take its course :~) indeed if you
beg some pond weed from someone with fish during summer you will probably
get the baby fish for free.

They appear!
