Cats are known for their night vision, unmatched jumping abilities and even nine lives, but what cat food tastes like to cats is not as well documented.

Scientists do know feline taste buds are far less complex than our own, and that's likely rooted in evolution. According to Scientific American, cats are the only mammals that lack taste receptors for sweetness. They do seem to have taste receptors for sour, bitter, salty, umami (savoriness) and possibly fat along with a taste for something we don't have: adenosine triphosphate (ATP). While researchers don't entirely understand this taste profile, ATP seems to be a signal for meat as it is the compound that supplies the energy in every living cell.

But how exactly do we know what cat food tastes like to cats and if they even like it? With wet vs. dry cat food, tuna vs. chicken, gravy vs. sauce and all the other choices out there, let's dig into the different types of cat food options and some of your cat's potential food preferences.

Types of Cat Food

There are three main categories of commercially available cat food, each in a variety of flavors:

Dry

According to Merck Veterinary Manual, dry foods make up the most popular type of commercially produced cat food in the U.S. and other countries. Also called kibble, these foods generally contain about 90% dry matter and 10% water. They are available in a variety of flavors and specialty formulations, such as indoor cat formula and hairball formula. Some dry foods are formulated to help prevent dental calculus accumulation.

Canned

Canned cat foods contain closer to 70%–80% water and 20%–30% dry matter. Wet cat food is safe to be refrigerated for up to three days but is not stable for long when left at room temperature. Because cats typically eat many times a day, instead of in one or two large meals, uneaten wet food is prone to forming a crust on the outermost parts as it dries up, decreasing both its palatability and convenience, as the dishes have to be repeatedly cleaned.

Soft-Moist or Semi-Moist

These types of cat food are what they sound like: softened kibble pieces that aren't dry and crumbly but also aren't wet and soggy like canned food. They often come in pouches, and their ratios of water to dry matter are 25%–40% to 60%–75% respectively. The advantage these have over wet food primarily is the convenience factor since they usually don't require refrigeration and their preservatives assure shelf life.

Food Preferences for Cats

• Flavors: While cat food flavors are available to suit even the most finicky of feline palates, from ocean fish and tuna to rabbit or chicken and beyond, the actual taste may matter less to cats than the food's nutrition. Food & Wine magazine cites a 2017 scientific study finding that, over time, cats seemed to initially select foods for flavor but then began to seek out the foods with an ideal protein-to-fat ratio regardless of flavor. Still, before purchasing any food in a large quantity, you might consider asking your veterinarian for samples or simply buy the smallest size product available to see how it goes with your own picky eater.
• Texture/Formulation: When it comes to wet vs. dry cat food, most cats seem to prefer softer wet options over dry or semi-moist kibble. It is very common for cats to not eat wet food that has been out all day and has started to dry up. Though it isn't entirely understood why cats think wet food is superior, it may be because it has stronger scents than dry food.
• Temperature: According to Cook's Illustrated, scientists have discovered that proteins in human taste buds are quite temperature-sensitive, performing far better at warm (but not too hot) temperatures. This means food seems far more palatable when it's heated. While this limited-topic study focuses just on humans, it may also apply to the feline world. When higher temperatures are applied to food — regardless of who's eating it — scent molecules are released and diffused, further increasing its appeal. If you decide to warm up your kitty's meal, only heat the food briefly and always check to ensure the temperature throughout is not too hot before serving it.
• Supplements and toppers: While liquid supplements or powder toppers have their place, especially when a feline is suffering from a chronic illness and reluctant to eat foods, it is generally best to avoid these food additives. Commercially available foods are already nutritionally balanced. Nutrient excesses are a common problem and can be as harmful as deficiencies. If you do want to use a food additive, it's a good idea to check with your vet first.
