P.S. ;-)

Checked your address (google doesn't show them
automatically) and see you are in the UK.

While bullfrogs and greenfrogs are not native to the
UK unfortunately bullfrogs have shown up thru import
and pet releases. So they still could be bullfrogs...
but probably not.

Bullfrogs don't like to start breeding until it gets
nice and warm out and as I recall one early summer
I spent over there, it isn't that warm this early!

Also you would have noticed their calls, which are
a 'run, run, run' very deep for a frog ;-)
