Best Cat Foods On The Market

Cats are carnivores, not omnivores like dogs and people. That’s the most important thing to keep in mind when considering what to feed yours.

“When it comes to nutrition, they are very inflexible, and owners must realize that,” says Louise Murray, DVM, vice president of the ASPCA’s Bergh Memorial Animal Hospital in New York.

Frequent Questions About Cat Nutrition

  • Should they eat as they would in the wild?
  • Should they avoid carbs?
  • ​Should they eat dry food for the health of their teeth?
  • Should they eat wet food for better hydration?

Some of these opinions are myths, some are based in science, and some are in between. Even scientists don’t agree whether some plant-based protein is acceptable for cats or whether plant-based ingredients are harmful to them.

Cat Scientist Doing Experiments

One thing is clear: cat food should be chosen for its ingredients and not for weasel marketing words such as premiumsuper-premiumnaturalcompletebalanced, which are not based on any standard.

What Are The Good And Bad Ingredients?

According to Anna Shoveller Assistant Professor, Dept of Animal Biosciences, University of Guelph, “There is no evidence that grains or other carbohydrate-containing ingredients are good or bad for cats. What is most important is that the cat’s protein requirement is met first.”

This means that healthy cat foods feature meat as their first listed ingredients. Plant-based foods are okay for dogs but are not good for cats.

Cats have a few other special requirements:

  • They don’t drink enough water so they should have both canned food and dry
  • They need digestible (high quality) ingredients in order to absorb the nutrients – it’s not the % of protein that matters so much as what it is
  • ​Small amounts of some carbs may help them digest their food and promote kidney health—the debate rages on—but a diet high in low-quality carbs is definitely hard on their kidneys
  • Low quality ingredients in general are hard on a cat’s health
  • Rendered fat – cheap way to add the required fat
  • Additives – color, flavor, thickening agents
  • Sugar
  • Thickening agents – carrageenan, xanthan gum
  • Ocean fish can be an allergen for cats, may contain toxins, and may also be fished by slaves

If you want to try:
