Cats should not eat chips. Potato chips are high in salt and fat, which can cause dehydration, kidney problems, and digestive upset such as vomiting and diarrhea in cats. Some chips also contain onion or garlic powder, which are harmful to cats and can cause anemia by damaging red blood cells. While eating a small amount of chips accidentally is unlikely to be fatal, chips provide no nutritional value to cats and are generally unhealthy for them. Regular consumption can lead to obesity and other health issues. It is best to avoid giving chips to cats and stick to cat-appropriate treats and food instead.
