A) it's a frog and B) I would say it's stone dead !!!! lol

Agree with Badfish dead as a doornail

Hmm dinner....

Yuck!! Unless you are a seagull.

or a crow/magpie/jackdaw/jay etc

That frog has been dead for a while Catty...

Hallo all. Thanks for your answers. Thanks Badfish for telling me it was a frog. It looked very dead to me as well and this morning it was still in the same place...so very dead...so I got a spade and threw it into the woods. I just wondered what could have killed it...cats, we also have a big colony of crows/ jackdaws in the woods so maybe they got it...but still the mystery remains.

Old age?

Doesn't look like 'natural causes' although it is a big frog.
As a thought, Rogi, do you use blue slug pellets in the garden? If the frog had feasted on a killed slug then that could have finished him off.

But then, what do natural causes look like in a frog?

No idea Cammomile but Bulba obviously does :)

@Bulbaholic...no I don´t use blue slug pellets or any other chemicals...I make compost tea, nettle tea to feed the plants on....but maybe it came from a neighbours garden that uses slug pellets.

'Natural causes', an animal or amphibian would normally crawl away to die quietly. This one seems to be rather 'splatted' on the ground!
