Ah, thank you very much!
The squash had some butter and cinnamon on the top, so I cut all that off. I tried offering some to her, but she completely ignored it. I mashed it up with my fingers, but she still won't even lick it...
Which leads me to my next question.
How should I feed it? Mashed up or straight?
What about the rind? I saved that, too, but I don't think it would pass through her digestive system nicely...well, it was worth asking.
