Is sweet dumpling squash okay?
 

I know that pumpkin is okay for cats and I've on occasion given my gang some butternut squash. Today I bought a small sweet dumpling squash at the market and set it on the counter. I just want into the kitchen and saw that someone had nibbled half the top! They ate most of the skin. Is it okay for them to eat the skin? I don't even know which of them ate it.
