I'd never consider it myself. Then again I'm a vegetarian and have been so since age 8. I don't enjoy eating meat. To be honest the only people I could understand eating animals/pets would be farmers. There are so many other ways to remember your pets than eating them.
To the original poster Mantis, if it's ok to eat pets after they pass away how do you feel about humans who wish to do the same with the remains of a family member? I remember once hearing on the radio about a family that had a rather unusual bbq.
Basically I argue that if it's not ok to eat human family members remains it shouldn't be ok to eat the remains of animal family members either.
