My cat licked a grape. Is grape juice toxic? What should I watch for?

Hi there. About 3-2 hours ago I was eating some grapes while my cat sat on the floor. Without thinking I rolled her a grape and watched her bat it around, but I would quickly step in whenever she would get it in her mouth. I had just remembered that grapes are apparently toxic to cats, so I decided to look it up and the results were terrible. She didn't eat one, though I'm worried if she got some juice from licking and it being in her mouth. She's acting fine but I just would nt mind being sure.

The tiny bit will likely pose no serious risk of toxicity. Monitor for lethargy, vomiting, diarrhea, a change in thirst or a change in urination. Unfortunately, an exact toxic dose for grapes has not yet been determined.
