People wondering if cat food is safe for dogs to eat and vice-versa may be interested to hear that a vet claims the foods are not interchangeable.
In an article on USA Today, small-animal veterinarian Patty Khuly has revealed that many people think it is alright to feed their cat dog food and their dog cat food but that this is not the case.
Dr Khuly claims there are a number of ingredients in cat food that are not good for dogs and the same is true of dog food and cats.
Examples include Taurine, which is needed by cats so is included in their food. As dogs can produce this amino acid, it is not present in their food. A deficiency in Taurine can lead to heart disease in cats.
Dr Khuley revealed that although a diet of cat food will not necessarily cause this sort of problem in dogs, it is far from ideal.
The vet wrote: "Although a dog can live on cat food alone (unlike cats and a lifetime of dog foods), it's not considered advisable. The caloric density, high protein levels and heavy doses of fat aren't ideally suited to all canine gastrointestinal tracts - or to their waistlines.
"More than anything else, cat-food-eating dogs tend towards the obese and suffer more gastrointestinal ailments than others."
