I had a Greek pasta salad for dinner and had finished most of it off, set it aside and Sorrel jumped onto the table to lick the bottom of the bowl. She wasn't chewing anything (as far as I could tell), and I only noticed her licking the bowl when I heard the scraping of the bowl against the counter for a few seconds. The onions at the bottom of the bowl are about the size of my pinky nail...if she licked one or even swallowed a small piece like this, should I be worried about Heinz body anemia or onion toxicity? There are so many horror stories out there about cats and onions...plus some sources say raw are more toxic, while others say cooked onion or powdered forms are worse. I think she only licked some of the dressing, but I'm a real worrywart and I just want to know if I should be looking for toxicity symptoms over the next few days.
