They would have enjoyed the guts, too. Toss it out there. Retrieve whatever they don't eat.
I put out a lot of things just to see what they would eat. Some things are ignored, but they eat almost everything.
We broke open more than a dozen pumpkins last year for them. Eventually, they ate everything but the skins of the pumpkins. They were so thorough that only one pumpkin plant sprouted this year.
