Taxidermy involves skinning the animal and putting the hide on an artificial body. There is nothing edible. The hide has been cured so it is also inedible.

None.

Here is a film of eating the equivalent of a taxidermied animal.

The same amount that you can find in leather shoes.

You can eat the skin and fur but I don’t recommend it. People have eaten leather boots, dirt, rocks and all kinds of things when starving. Tree bark, too. Even dogs will eat leaves and rocks when abandoned and starving.

My favorite taxidermist in Connecticut was Gene Pitney, yes that GenePitney. I also worked with for many years with his brother Frank. Gene did a Large Mouth Bass for one of my high school buddies.

There is no meat. It has all been removed and replaced with jute and/or other types of stuffing. Only some bones remain, like the skull.

Stuff it with cheeseburgers and use it for a pinata?
that’s all I’ve got
