I ate python last summer, and I'd eat it again...
But NOT one of mine, or any of my pets for that matter. I don't see animals I'm eating as animals so much as just food. I never held them, looked into their eyes, watched them swim, bonded with them or named them. They're just food. But one of my pets, no way...
My deceased animals are all buried (mostly fish). I don't see it as a waste. I see it as a final goodbye.
