You've got to be Kidding!

This photo is part of a series I caught this morning when Gracie T-t wanted to walk along the deck rails as she did before the snows came. I cleared a wee spot and she sat there looking at the snow then away as if to express her disbelief. The next three (missing) photos show her jumping right across the top of the snow and then sinking.
She is having a difficult time with this seasonal change. Every day she goes outside with hope in her heart to run across the lawn and nibble on fresh grass tips. Alas... no grass. But, GT-t remembers the flat walkways on the top rails and this white cold stuff does not belong!
Can cats feel disgusted?
