Can dogs and cats eat xylitol (artificial sweetener)?
Quick verdict for Xylitol (artificial sweetener): see below the answer for dogs and for cats, the symptoms of poisoning (when applicable), and what to do if your pet ate it anyway.
Toxic
In moderation
Note: the verdict is different for each species — read the full explanation below before offering xylitol (artificial sweetener) to your pet.
Why is this the verdict?
Xylitol is an artificial sweetener found in chewing gum, candy, some peanut butters, 'sugar-free' products, mouthwash, and diet baked goods. In dogs, xylitol is absorbed rapidly into the bloodstream and tricks the pancreas into releasing a massive burst of insulin, causing a sharp, dangerous drop in blood sugar (hypoglycemia) within 30 minutes to 2 hours — larger doses can also cause acute liver failure, sometimes fatal.
In cats, recent studies indicate that the toxic mechanism seen in dogs (insulin release) doesn't appear to occur the same way, and the ASPCA states that cats aren't affected in the same manner. Even so, because this is an area with limited data and given the seriousness of the risk in dogs, the prudent recommendation is to keep xylitol-containing products away from any pet.

For cats: although the risk appears lower, contact a veterinarian as a precaution, especially if there's any sign of illness.
