Cats and sweets

Randomly, I wondered whether or not cats can taste sweet things. According to this link, they cannot. Apparently they lack the gene and the taste receptors, whatever that means. Actually, my wondering wasn't so random. My cat keeps trying to get my grapes, but when I finally offer them to her, she turns her nose up at them. I suspect it is because there is still water on them from when I washed them. Or perhaps she just wants to play with them. In ane event, there is my random thought for the day.
