Although cats can eat apples, that doesn’t mean they should.

Can Cats Eat Apples?

Does the old aphorism, “An apple a day keeps the doctor away,” apply to cats?

Probably not.

Cats can eat apples, but that doesn’t mean that they want to or should. Since cats lack the receptors to taste sweet things, only a select few cats will enjoy the soft, crisp texture and appreciate them as a healthy snack. However, if your cat is interested, apples are not toxic or considered dangerous. Cats are obligate carnivores and the nutritional benefits of apples for them are minimal at best. In humans, apples are considered a low-calorie food high in fiber, vitamin C, and antioxidants. The antioxidants in humans have anti-inflammatory, anticancer, antiviral, and antidepressant benefits, as well as the ability to lower blood sugar, and improve muscle strength and brain function. Benefits of apples have not been well documented in cats.

The Dangers of Apples to Cats

Ingestion of large amounts of apple can cause gastrointestinal upset, such as diarrhea. Although uncommon in cats, ingestion of apple stems, seeds, and leaves can be toxic, since they contain small amounts of cyanide. The leaves and stem are also difficult to digest and can lead to gastrointestinal irritation or obstruction. Signs of toxicity or indigestion include vomiting, diarrhea, lethargy, abdominal pain, straining to defecate, or decreased appetite.
Choking is also a danger for cats – especially when eating a larger-sized piece. Some cats are not good at “chewing” their food, and apples certainly pose a risk, due to their size and texture.
Also, be careful to avoid anything apple flavored that contains the sweetener xylitol. Although primarily an issue in dogs, many veterinarians believe it is safest to avoid giving your cat products that include this sweetener. Xylitol is a common ingredient in diet or low-calorie pastries, applesauce, and drinks. Learn more about xylitol toxicity in dogs here.
