The Best Cat Food: Introduction

Garbage in, garbage out – nowhere does this saying apply more than when it comes to feeding our cats. Here in the United States, The FDA strictly regulates the food we eat to ensure it’s safe. Sadly, the bar is much lower when our pets’ food is concerned.

Many store brand cat foods contain a laundry list of chemicals, preservatives, and artificial ingredients. Not to mention things like grains, yeast, and fillers such as clay – stuff we wouldn’t dare put in our own food. So why feed it to our beloved, furry family members?

Aside from routine trips to the vet and adequate playtime, a healthy diet is the primary way you can help your kitty live his or her best life.

Balance is Key

The best diet for your cat is one that is protein-forward, consisting primarily of meat.

That’s because cats are obligate carnivores, a phrase you’ve likely heard before. To function properly, their bodies need certain nutrients like taurine, vitamin A, and arachidonic acid, which are typically found in animal tissues.

We need to be careful though to avoid oversimplifying their nutritional needs. Although they are carnivores, feeding our cats nothing but meat would eventually lead to deficiencies of several key vitamins and minerals.

Fortunately, most high quality commercial foods contain everything a cat needs to thrive. But this doesn’t mean you should feed them the same thing every meal.

Exposing your cat to sufficient variety with regards to flavors, textures, and protein sources will serve them well later in life for a number of reasons.

The Thirst is Real

Proper hydration is perhaps the most important aspect of optimal feline nutrition.

In the wild, cats have evolved to rarely drink water. That’s because their diet (small rodents and other prey) provides them with sufficient water to meet their body’s needs.

Since our pet cats are probably not subsisting off of live animals, it is on us to provide them with adequate access to clean, fresh water.

Fountains can also encourage them to drink more, as many cats will quickly lose interest in water that has been standing for a while.

Cat Nutrition: Macros & Micros

Just like us, cats need to consume a variety of macro and micronutrients for optimal health. There are some notable differences, however, particularly around carbohydrates.

Additionally, some foods that are safe or even healthy for us can be toxic to our pets.

Proteins

When it comes to macros, protein is king. In the wild, cats consume around half (52%) of their total calories in the form of protein. Its presence in sufficient quantities is necessary for growth, maintenance, and repair of body tissue.

Protein also serves a crucial function inside a cat’s body as enzymes and hormones; they cannot survive without it.

Fats

Fats provide the most concentrated source of energy since they have more than twice the calories of proteins or carbohydrates. Left to their own devices, cats will consume a bit less than half of their calories (46%) from fats.

Sufficient dietary fats are necessary for proper brain function, as well as regulating many important hormones. Additionally, they supply essential fatty acids and aid in nutrient absorption.

Carbohydrates

It was once a widely held view that carbohydrates are bad or even harmful for domestic cats’ consumption. This is partly due to the fact that in their natural habitat, cats only consume a tiny portion of their overall calories from carbohydrate sources (2%).

While this is no longer the prevailing belief, carbs should only account for a minimal part of your cat’s diet. This is especially true for starches – overconsumption of them can lead to serious health problems, including kidney failure and diabetes.

Vitamins and Minerals

Micronutrients are required for many important biological processes. Minerals like calcium and phosphorus are essential for strong bones and teeth. Vitamins are necessary for boosting immunity, as well as supporting healthy growth and development.

Some commercial cat foods are fortified with vitamins and minerals, but this is often unnecessary. Simply feeding your cat a high quality, protein-forward diet with enough variety should be sufficient to satisfy their micronutrient needs.

Life Stage Considerations

The best food for your cat will be heavily dependent on their age or stage of life. Generally speaking, cats have three distinct life stages:

• Kitten: 0-12 months
• Adult: 1-7 years
• Senior: 7+ years

Luckily for us, most commercial cat food is already optimized for a specific life stage. We just need to be careful when reading the labels to select the right one. However, there are still some important differences to keep in mind as your cat goes through life.

Best Food for a Kitten

• Cats are considered kittens for their first year of life. During this time it is crucial that they are fed food specifically formulated for kittens. Kitten food uniquely contains the correct balance of nutrients for their growing bones and body.
• Most kittens begin eating solid food at around three weeks of age, supplemented still by their mother’s milk. Young kittens need many small meals throughout the day to sustain their energy levels.
• Around eight to twelve weeks old, most kittens are ready to find their forever homes. Continue feeding the same food they’ve been eating to avoid upset stomachs. If you do change their diet once they are settled, be sure to do it gradually.
• Over the next few months, you can reduce the number of times you feed them. Some cats will be happy with just two meals a day by the time they are six months old, though it can be beneficial to wait until closer to the one year mark.

Adult Cat Nutrition

• A cat is considered adult from one year until approximately seven to ten years-old.
• Adult cat food is often designed for specific lifestyles. For example, food for indoor cats, those that are neutered, and food for cats that need to lose weight.
• There are even special prescription diets for cats with a medical condition. Consult with your vet if you are not sure which food is best for your cat.

Best Food for a Senior Cat

• Cats are considered seniors once they have reached anywhere from seven to ten years old.
• Certain foods become more difficult to process as they get older, such as salt.
• Senior cat food is specifically designed to help support vital organs, such as their kidneys, as well as helping them maintain weight and lean muscle mass.
• It is important to monitor older cats closely to keep an eye on their daily intake. If they begin eating less or drinking more it could be a sign of a health problem such as kidney disease, gingivitis, or diabetes. Contact your vet immediately if you notice a sudden change in their habits.

Dry Food vs. Wet Food

When it comes to the best diet for your cat, there is nothing more contentious than the debate over dry food versus wet. Both sides have their pros and cons.

On convenience, nothing can compare to the ease and shelf stability kibble has to offer. Yet it is far less healthy and biologically appropriate than many commercially available wet foods.

There are also cost considerations, since wet food is typically more expensive than dry. On the flipside, dry food is often linked to dehydration, which can cause more serious issues such as kidney disease.

It quickly becomes evident that there are tradeoffs with either decision. Your unique circumstances might favor one format over another, but we find that some combination of wet and dry is optimal for most cats.

If you are unsure what to feed your cat, have a conversation with your vet to determine what is best for your situation.

Dry Food (Bad)

Dry food remains the go-to choice for many cat guardians, despite the growing body of evidence pointing to it’s deficiencies. It is typically the cheapest option and by far the most convenient, but its convenience is also its greatest weakness.

That’s because protein is not usually shelf stable at room temperature. And as discussed already, our cats need lots of protein. So commercial pet food manufacturers came up with a way to solve this problem – they invented kibble.

Dry cat food contains various fillers, binding agents, and preservatives that make it shelf-stable for months or even years in one’s pantry. Broadly speaking, kibble is the nutritional equivalent of feeding your cat McDonald’s.

Pros: Convenient, less expensive, best for dental health.

Cons: Can be high in carbohydrates and other grains, fillers. Highest obesity risk. Minimal moisture content increases the risk of dehydration.

Wet Food (Better)

Pros: Higher in protein and moisture than dry food, closer to a natural diet.

Cons: More expensive and less convenient to store and serve vs. kibble. Must be refrigerated once opened.

The Real Diet (Best!)

Pros: Highest in protein and moisture, minimal additives and carbs, closest thing to a natural diet.

Cons: Generally the most expensive and least convenient to store and serve.

Notice we didn’t say, “raw”, even though it would probably be closest to a cat’s natural diet. That’s because any benefits are easily outweighed by the significant health risks undercooked meat can pose to your kitty and even you.

Instead, we prefer “real” food. There are several semi-raw or lightly cooked foods that fall under this category. Our favorite is Smalls, which is what we primarily feed our own cats.

Different Strokes

For most guardians, some combination of these will be optimal and the mix will depend on your cat’s individual needs. Always check with your veterinarian first before making significant changes to your cat’s diet.

Feline Nutrition: Other Important Considerations

How to Change Your Cat’s Food

“How do I switch my cat’s food?” is the question we typically get at around this point in the conversation. And our response is always the same, slowly.

Cats are highly skeptical of anything new, and for good reason. In the wild, new is often synonymous with danger. In addition to this innate skepticism, cats also have sensitive stomachs. So we must be mindful and deliberate if we wish to succeed.

Swapping a cat’s food with a totally different format/brand cold turkey is not recommended. This can cause an upset stomach, vomiting, and diarrhea, just to name a few. Instead, we want to transition gradually, over the course of a few days or a week.

Start by feeding them their normal food, but put a small amount of the new food in their bowl as well. Once they are comfortable with its flavor and texture, you can gradually begin to increase the amount of new food and decrease the old with subsequent feedings.

When you get to 3/4 or so of the new food, you (and your kitty) are probably ready to fully make the switch.

Variety is the Spice of Life

“Creature of habit” might even be an understatement when cats are concerned. Find a food that they fancy and there’s a good chance that they’ll be content eating this, and this only, for the rest of their nine lives. This is especially problematic if that one food is kibble.

I inadvertently did this with my first cat and it came back to haunt me. Please, don’t make the same mistake that I did. Ensuring that your cats have variety in their diet is important for multiple reasons.

First, having a diverse intake helps ensure your cat is getting all of the essential vitamins, minerals, and nutrients he needs to stay healthy. Next, it will reduce boredom. Many cats eventually tire of eating the same thing and will then completely shun it.

Last, a situation we never want to think about – if something were to happen to us. Cats can become anorexic and refuse to eat if they suddenly find themselves in an unfamiliar place, particularly if they are used to eating only one thing and suddenly it’s not an option.

Free Feeding for a Fat Feline

Free feeding, the practice of having dry food available at all times, can lead to overeating and obesity. It’s important to regulate your cat’s food intake and provide portion-controlled meals to help them maintain a healthy weight.

Not to mention that it’s completely unnatural. Having access to a bowl full of heavily processed kibble 24/7 is as normal to your cat as hunting for dinner with nothing but our bare hands would be for us.

Finally, it makes training next to impossible. Food is by far our best (often only) weapon when we’re in the kitty classroom. I’ve foolishly made this mistake before and can verify that a cat with a bowl full of kibble will be unmotivated to do even the simplest task for a treat.

Speaking of treats…

On Treats

Hopefully you are sitting down before you read what I’m about to write.

Stop giving your cat treats. Ok maybe not altogether, but you should definitely stop giving them treats just for being ridiculously cute.

That’s because when it comes to asking for our cats’ obedience, treats are by far the most effective tool we have. Unlike dogs, who often cooperate just for praise or their owner’s approval, food is, for most cats, the only motivator with any teeth (pun intended).

Furthermore, even treats are nearly powerless if you are still free feeding. I learned this the hard way with my first cat, who would acknowledge then ignore my requests before leisurely strolling over to her kibble, glaring at me as she cronched away in disobedience.

If kibble is the equivalent of fast food for our cats, then unhealthy treats (ahem, Temptations – we’re looking at you) are like Twinkies. Deep fried ones, folks.

Things You Should Never Feed Your Cat

People are often surprised to discover that some of the normal, everyday items in their pantry or fridge are toxic for their pets. Something as seemingly innocuous as a piece of chocolate can be harmful or even fatal.

There are also several fruits and vegetables (see below) and a long list of houseplants that are highly poisonous to cats.

Additionally, the following is a list of things you should never feed your cat:

• Caffeine (Coffee & Tea)
• Milk & Other Dairy Products
• Chocolate
• Raw Eggs, Meat and Fish
• Avocados (mostly the pit but even the fruit is toxic in high quantities)
• Grapes (and Raisins)
• Garlic, Onions, and Shallots
• Leeks, Chives, and Scallions

If you suspect your cat has ingested one of these items, immediately contact your vet or animal poison control for further guidance.

Best Food for Your Cat: Conclusion

The best food for your cat is one that is age and lifestyle appropriate.

It should be protein-forward with healthy fats, essential vitamins and minerals, and sufficient variety. Whether you ultimately choose dry, wet, real, or some combination of foods, always prioritize your cat’s health and consult with a vet for personalized advice.

By mindfully choosing what to feed your cat, and ensuring that they eat a balanced diet comprised of high-quality ingredients, you will be doing both of you a huge favor.

On the one hand, proactively prioritizing their health will help avoid costly trips to the vet.

On the other, you will be giving them the best, longest life possible. And what better gift is there than that?

Happy feeding.
