Welcome to Feline Nutrition

There are many things that go into keeping your cat healthy and happy. Genetics and environment play a part. But, there is one thing that has a huge effect on your cat's health, and that is diet. Cats are predators that evolved to eat a diet of raw meat. It is only over the past 70 years or so that we have tried to feed cats a diet based on foods unsuitable for a strict carnivore. Grains, vegetable and plant matter and highly processed and cooked meat products. It's no wonder cats suffer from so many diet-related diseases. We're out to change that.
You are here because you want to learn more about how to keep your cat healthy. Diet is the most important change you can make in your cat's life. We hear over and over again from pet parents who have changed their cats' diet and now wish they had done it sooner. They can't imagine feeding their cats any other way. Not only do they see improvements in their cats' health, but they feel a great sense of relief knowing they control what goes into their cat. No more mystery ingredients. Contemplating a diet change for your cat can be a bit overwhelming at first. We remember what it was like in the beginning. We were used to leaving our cats' nutrition in the hands of others. But, leaving it to others didn't work out so well, did it? Cat nutrition is complicated, right? Well, not really. It's actually pretty easy.

Answers: Flaxseed Oil for Kitty?

I know cats need omega-3 fatty acids, as we humans do. I take flaxseed oil supplements myself for the fatty acids they contain. Can I give flaxseed oil to my cats?
The quick answer is yes, but it's not a good idea. Fatty acids are one of the most common supplements given to cats and dogs. Omega-3 fatty acids tend to reduce inflammation, while omega-6 fatty acids tend to increase inflammation.¹ There are also omega-7 and omega-9 fatty acids, but, they are not considered essential, at least for humans.
Fatty acids are abundant in the oil from fish, but are also found in many plant sources such as the oil from flax and soybeans. Some nuts and green vegetables also contain omega fatty acids, such as walnuts, Brussel sprouts, kale, spinach and some salad greens. But, the form these fatty acids take is the crucial difference when it comes to cats. Cats evolved eating prey diets rich in animal fat, which contained omega-3 and omega-6 fatty acids in the pre-formed state. The prey animals had already converted plant-sourced ALA into EPA and DHA for them, so cats lost the ability…

Answers: Lysine and Raw Meat Diets

What is lysine? I have a friend who gives it to her cat as a treatment for herpes, but should it be supplemented in every cat's diet?
Lysine is an essential amino acid for cats. This means that the cat's body cannot synthesize or make this amino acid so it must be consumed in the diet. Lysine is present in all meats, but fish contain higher amounts than other types of meat. For many years in human medicine lysine has been used to help suppress herpes flare ups and several studies exist to support this.¹ It is suspected that the mechanism by which lysine is able to suppress herpesvirus is by competing with arginine. Studies have indicated that arginine is necessary to signal and initiate replication of certain viruses including all herpesviruses. It is thought that lysine displaces arginine and thus interferes with this process. Several studies indicate that lysine may be effective at suppressing feline herpesvirus, a common cause of upper respiratory and eye problems in cats.² Since arginine is also an essential amino acid for the cat, there has been some concern that too much lysine may result in an arginine deficiency. Arginine deficiency can make cats very sick.

Eight Cat Curiosities

I have had cats my whole life. Except for a brief period in my younger days in a no-pets apartment, they have always been there. There are pictures of me as a baby snuggled up to a kitty bigger than I was. As a child, my father insisted that the cats go outside at night - sigh - it was a different era. But, I kept the window open in my room to let them back in.
One of the most heartbreaking experiences I ever had as a child was leaving a house we stayed in for the summer without one of our cats. Tigger, at the time less than a year old and not neutered yet, ran away or got lost in the woods days before we had to leave. We searched valiantly, but could not find him. We hoped a nearby farmer had taken him in, but we never knew what became of him. In the following summers though, we did see feral cats around the area that looked suspiciously similar to him. We had not seen strays around before, so we hoped this was a sign that he'd survived and had even found some lady friends. You would think that having spent my life around cats, nothing about them would surprise me. But, that is wrong.

Nutrition is Vital for FeLV Cats

The feline leukemia virus, generally referred to as FeLV, is classified by virologists as a retrovirus. A retrovirus uses an enzyme called reverse transcriptase to insert copies of its own genetic material into the cells it has infected in order to produce a new copy of a whole virus. Infected cats can be found everywhere, but the prevalence varies depending on many factors: age, health, reproductive status, concurrent disease, environment, lifestyle, etc. The worldwide prevalence is about 5% of free-roaming cats. In the United States, approximately 2 to 3% of all cats are infected with FeLV. The rates rise significantly, above 10%, in sick cats, youngsters, or cats otherwise at high risk of infection.¹
Cats with persistent FeLV infection serve as sources for the spread of the disease. Virus is shed in large amounts through bodily fluids: saliva and nasal secretions, urine, feces and milk. Cat-to-cat transfer of the virus may occur from a bite wound, during mutual grooming and less often by sharing litter boxes and feeding dishes. In utero transmission can also take place from infected queens or while they are nursing.

Recipe: Feline Nutrition's Easy Raw Cat Food

Making raw cat food at home isn't hard to do at all, anyone can do it. Once you make your own, you will realize that raw cat food isn't complicated. It helps to know how ground raw diets are made, because commercially made frozen foods are made in much the same way, just on a larger scale. Taking the mystery out of what you feed your cats is important. While your cats benefit from the nutritionally better food, the benefit to you in terms of peace of mind shouldn't be overlooked.
What does a homemade ground raw meat diet consist of? Most importantly, it is more than just meat. Ground raw meat diets for cats consist of meat, organs, bone, fat, egg yolks, water and supplements. All are necessary to make the diet balanced. The goal is to mimic the natural prey-based diet of cats. Notice the lack of any carbohydrate-based ingredients. These are not needed in the diet of an obligate carnivore. Making your own raw meat diet gives you control over what goes into the food, allowing you to select the meats and supplements you use.

No Bull, Taurine Is a Must for Kitty

I am sure that you have all heard about the importance of taurine in a cat's diet. Taurine is a naturally occurring amino acid mostly found in muscle meat and organs like heart, kidney and liver and in seafood. In muscles, taurine gets more concentrated the harder the muscle works. Dark meat has more than light meat because it comes from parts of the body that work harder, legs as opposed to breast. Heart is another great example. Although it is termed an organ, it is really the hardest working muscle in the body and it has one of the highest concentrations of taurine. Shellfish such as mussels and clams also have a lot of taurine. They are constantly filtering and they follow the same "hard-working" scenario, concentrating taurine to a high degree in their tissues. Small amounts of taurine are found in dairy products. Plant products contain either low or undetectable amounts taurine. Despite meat being a good source of taurine, there is a significant amount of variability within meat samples according to a published study.¹ Taurine content of meat was not only affected by diet, breed and environment, but also by the freshness of the meat. Cats, unlike some other carnivores and unlike herbivores or omnivores, are not able to synthesize all the taurine they need.

Constipation: Real Help for Your Cat

One of the immediate results when feeding a raw meat diet is less cat poop, and cat poop that smells less. While some cat owners welcome this change, some are concerned that their cats might be constipated.
Feeding a raw diet can closely resemble nutritionally what cats would eat if living wild in their native habitat, but, despite our best efforts, it is not a truly natural diet. The natural diet can only be replicated by feeding small whole prey. One of the biggest differences between feeding raw diets and the natural prey diet is: fur. Fur, ingested with prey, has no nutritional function, but serves two key mechanical functions which we lack when feeding a home-made raw diet. First, by action of the cat biting down on small prey, the fur of the prey is brushing against the teeth, helping to wipe away plaque and preventing accumulation of tartar. Second, fur has an important role as a non-irritating stool bulker. Unfortunately, fur is next to impossible to substitute in the raw meat diet, because adding hair or fur to a recipe would be difficult. Instead, people resort to a number of ingredients from plant origin to fulfill this need.

Don't Let Calcium/Phosphorous Ratios Scare You

It is widely known that cats have a dietary need for both calcium and phosphorous. Calcium is required by the body, not only for bones, but also for muscle control and ion balance. Phosphorous is important in the formation of bones and teeth, and also plays vital roles in cell membranes and energy processes. Phosphorus is a structural part of cells; this is why meat tissue has high levels of it. Phosphorus is attracted to calcium, forming calcium phosphate, which is what gives bones and teeth their strength.
Just as important, and possibly even more so, is the ratio of calcium to phosphorous in the diet. Like big cats, the domestic cat's ancestral diet of whole prey would serve to provide the proper amounts of both of these minerals in the ideal ratio. This is because by weight, the cat's typical prey consist of about 7-10% bone.
What is the ideal ratio and how can you ensure that your cats are getting proper amounts? Calcium to phosphorus ratios are typically written like this: 1.1:1, with the first number representing calcium and the second phosphorus.

Answers: Kittens Go Through Teething, Too

I am getting two new kittens soon. I plan on feeding them a raw meat diet, but should I wait until they are older and have their permanent teeth to start them on small meaty bone cuts? Can their baby teeth tackle chicken wings or necks?
We are often asked about the special dietary requirements of kittens. Ideally, your kittens should be weaned directly to a raw meat diet. We suggest that as soon as your kittens arrive they should be introduced to raw meaty bones. Get those little critters gnawing and chewing as soon as possible. It is so much easier than trying to transition them later. Raw meaty bones provide a natural, highly digestible source of calcium. Calcium in raw bones can be up to four times more digestible than any supplement. Because the high levels of phosphorous in fresh meat need to be balanced by plenty of calcium, nature has perfected the balance already. Raw meaty bones supply calcium and phosphorous in perfect combination – no need for guess work and formulations. The young kitten, when supplied with an adequate amount of raw meaty bones, will use exactly what it needs for growth and development, and excrete any excess.

Cats and Cantaloupe: A Method in their Madness

One of the things that we hear about all of the time is the strange things that cats will eat. If you've had cats for any length of time you have undoubtedly experienced this. Not just the odd items in the meat category, such as grasshoppers and frogs, but also things like broccoli and string beans. However, the single food item that seems to come up again and again is cantaloupe. Having a cat that wants to eat something unusual now and then doesn't seem that implausible. They are individuals and subject to the variations in behavior that entails.
But to have cats from all different parts of the world, in the past and the present, seemingly unable to resist cantaloupe, has to be more than just coincidence. Something is going on.
Being naturally curious – okay, I confess, maybe irrationally curious – I decided to investigate what's up with cantaloupe. When I looked around, there was lots of speculation: it's the texture, the taste, the moisture. I remember as a kid, we had a cantaloupe-obsessed cat. She was not allowed on the dining table. In fact, she never jumped on it, ever.

Answers: Plant vs. Meat — The Protein Feud

I have read that plant proteins are inferior for cats, that they need meat protein. What's the difference? Why does it matter where the protein came from?
Not all proteins are equal. Proteins are made up of amino acid chains and there are a myriad of different combinations that serve many functions in the body. Proteins are structural and tissue components in the body, enzymes and antibodies and serve messenger and transport functions. Ingested proteins will vary considerably in how well they are utilised by the body. Plant-based proteins do not have the same amino acid profile as meat-based proteins and these differences are crucial to cats. The natural diet of cats in the wild is a meat-based diet of rodents and birds. Cats are metabolically adapted to preferentially use protein and fat as an energy source, not carbohydrates. There is a substantial difference in protein requirements between our cats as obligate carnivores and other carnivorous species, such as the dog. Adult cats require two to three times more protein than adults of any omnivorous species, such as humans.

The Myth of the Finicky Cat

One of the questions I get asked most frequently is what to do about a cat that doesn't want to eat the new raw meat diet you are offering. I hear words like "stubborn" and "finicky." While that may describe what's going on, it is from a decidedly human perspective. I think it's time to delve into a little cat psychology to help us understand what's happening in that little kitty brain.
People like to say that cats are creatures of habit. I would agree, but habit isn't quite the right word. Cats stick with what works. That kind of behavior makes a lot of sense for them and they learn what works pretty early in their lives. It's especially true when it comes to food. Notice I say "learn." While cats are predators and have a hunter's natural instincts, those instincts are basic. They learn the nuances and details as they grow up. All that cat play behavior is essentially practice for the hunt. They may look like they are just having fun, but don't be deceived, this is How-to-Be-a-Cat 101 for them. They are practicing the skills they will need to survive. In the wild, a mother cat would bring prey – either already dead or close to it – back to her kittens.

Feline Pancreatitis: Signs of Trouble

Pancreatitis can be a frustrating disease in cats. The cause in most cases can't be definitively determined and the symptoms can be vague. Pancreatitis can range from low-grade with mild symptoms to severe, which can be fatal. Most often, the treatment is supportive, alleviating symptoms and keeping the cat comfortable.
The pancreas is a lobulated gland located along a portion of the small intestine in mammals. The pancreas has two types of tissue, each one of them synthesizing a different type of secretion. The exocrine portion, or acinar cells, produce enzymes utilized in the digestion of food and the endocrine portion, or islets of Langerhans, produce vital hormones such as insulin. Insulin is involved in the absorption and metabolism of glucose.
There are several diseases that can affect the normal functioning of the pancreas. In this article we're going to talk about inflammation of the pancreas, which is called pancreatitis. Pancreatitis happens when the enzymes produced and stored in the exocrine portion of the organ get activated inside it.
