Q ONE of my cats insists [...]; Pets and their people Your amazing animals and wonderful wildlife.
BARTON replies: Eating dog food occasionally as well as her normal diet isn't a problem. However, there are some differences between dogs and cats in their needs for vitamins and essential proteins between dogs and cats. In particular, cats need the amino acid TAURINE in their food, which dogs can take from other substances. A cat fed exclusively on dog food will develop taurine deficiency, which can lead to serious problems including heart disease and blindness.
The large pet-food manufacturers have spent millions of pounds researching the best foods for our pets, so generally speaking, try to feed dog food to your dog, and cat food to your cat.
