With Halloween just around the bend, you and your family are probably looking forward to more treats than tricks. Those colorful, foil-wrapped delights can also tempt your feline family members, but cats and candy can be a dangerous combination. For their safety, keep your kitty away from your candy stash.
Dangerous Foods for Cats

Some ingredients commonly found in Halloween candy and treats can upset your cat's stomach, while others can be downright toxic. The ASPCA warns against the following foods in particular.
Chocolate
The ingredient that makes up the majority of Halloween candy — and the one that might just be the yummiest to your kids — is also one of the most toxic to your pets. Chocolate contains caffeine and the compound theobromine, both of which can cause vomiting, diarrhea, hyperactivity, heart arrhythmia, muscle tremors and seizures. The ASPCA notes that dark chocolate is more dangerous than milk or white chocolate, as it has higher levels of these harmful substances.
Dairy-Based Treats
Cats have low levels of the enzyme that helps the body digest lactose in milk and dairy products. While ingesting candy that contains dairy isn't likely to be lethal, it can cause an upset stomach, vomiting and digestive issues such as diarrhea.
Xylitol
This sweetener is used as a sugar substitute in many sugar-free candies and chewing gums. In dogs, xylitol is known to raise insulin levels and cause a severe drop in blood sugar, and it can lead to liver failure. While there aren't reported cases of this occurring with cats, Preventive Vet suggests this may simply be because cats are more discerning about what they eat. It's better to be safe than sorry and keep your cat away from sugar-free treats.
Raisins
There's always that one house that hands out boxes of raisins in place of candy. What's meant to be a healthy treat for your kids, however, can be unsafe for your pets. All types of raisins and grapes are known to cause kidney failure in dogs. While less common, according to the Animal Emergency & Referral Center of Minnesota, there have been reports of cats showing signs of toxicity after eating grapes and raisins. Keep those little boxes out of paw's reach.
