Ive never been able to completely understand why people get so uptight when dealing with corpses (of any kind). I recently saw where someone had shot a feral cat, which had been slaughtering their chickens.
The guy skinned it, and sold the skin online, and the shitstorm was astronomical!. To me, it was dead , and there was no more relevance to the ideology of a "pet cat" as there was to a useful floormat or hat lining. It was dead when skinned .....and dispatched humanely.
Personally I love skulls, I have heaps of them in my house, of animals and birds. I love the symmetry, and the look. Also love skins, and pelts, and teeth and claws and such. The only difference I can see is that whereas its me that enjoys them now, it was their original owners that enjoyed them and their use before. Is it ok to be fond of dead things? ...I say yes.
