I can lead her to water but I can't make her drink

Wild Hedgehog drinking (source)

I love Peggy, I really do, but sometimes I am concerned that she is ... not the sharpest quill on the hog. I am very diligent about giving her fresh water a couple times a day. What does she do on a hot summer evening with a bowl of cool, clean glacier fed water coming from one of the best sources on earth? She ignores it and instead chews the wet bits of bedding around the bowl. Why?! Do hedgehogs obtain moisture from leaves and forest junk in the wild and she is replicating that behaviour? Or is she just not smart enough to drink the clean water in the bowl?
