I didn't know possums were supposed to eat them too.
Possums will eat ANYTHING that does not resist being eaten.
One that I inadvertantly shut up in my garage for a couple days ate all the D-Con mouse poison (several boxes) in there, and chewed the nozzle off the plastic lawnmower gas can ..... he was loose in there 4 days, and was still alive when I found him .....
I have actually saw one that ate the ...... ummmm .... anus ...... out of a dead skunk. Drove by the roadkilled skunk in the early AM ..... passed by again a couple hours after dark, and the back half of this possum was sticking out of the back end of the skunk ..... he was chowin' down with enough gusto that the skunk carcass looked like it was alive and moving ....
Possums are such nasty creatures that the barn cats of my youth, which would fight you for chicken guts, would not touch a live, pink, hairless, defenseless baby possum.
