Why Understanding Safe and Unsafe Foods Matters for Pets
Feeding your dog or cat the wrong food can lead to more than just an upset stomach. Some human foods are perfectly safe, while others can be toxic or even life-threatening.
Pets process food differently than humans. For example, grapes may seem harmless to us but can cause kidney failure in dogs. Cats, being obligate carnivores, require high-protein diets and cannot tolerate certain carbohydrates and plant compounds.
Veterinarians consistently warn that pet owners should know the difference between safe, unsafe, and toxic foods to avoid costly vet visits and keep pets healthy long term.
