Cat food 101: What ingredients to look for

Are you a new cat owner curious about what to feed your cat? Or are you a well-seasoned owner with a precise cat feeding schedule, and you constantly ensure that what you’re giving is healthy cat food? Whether you fit in one of those categories or somewhere in between, we have just the guide for you. Keep reading to learn about what dry cat food ingredients are healthy and which aren’t.

Nutritional needs

When you think of a cat’s wild relatives, you probably think of a lion or tiger. Like their counterparts, domesticated cats need lots of protein. And they need certain nutrients, like taurine, that can only be found in animal, not plant proteins. Cats require particular types of fats, including linoleic acid, arachidonic acid, and DHA. They must also get a sufficient amount of various minerals and vitamins. Notably, cats do not need carbohydrates, which is why feeding cats grain is not recommended. Although humans use carbohydrates for energy, cats instead optimize the energy they get from proteins and fats to the point that carbs are not necessary.

The food of utmost importance in cat nutrition is meat. Every pet food sold in the United States must list ingredients in descending order of prevalence and must also display a guaranteed analysis of nutrients such as protein, fiber, and fat. These guidelines were decided on by the Association of American Feed Control Officials (AAFCO).

Protein ingredients

Since animal protein is crucial to a cat’s diet, it should be your priority when looking at cat food labels. Healthy cat food has some type of meat as the leading ingredient. However, it may not be called “meat” in the ingredients list, which should actually specify the animal the meat came from. Also note that meat by-product, bone or fish meal, and beef tallow are other sources of animal protein.

Fatty ingredients

As already mentioned, fats are another essential component of a cat’s diet. They produce twice as much energy as protein. Animal fats and oils are commonly used as a good source of various fats. Omega-3 and omega-6 fatty acids are also necessary and include compounds such as linoleic acid and DHA. Don’t worry about your cat getting too much fat; as long as they are fed an AAFCO-certified food, they are receiving a balanced diet.

Trace elements and the like

Unlike ingredients in human foods, the ingredients in your cat’s food that are hard to pronounce are usually necessary compounds, such as preservatives or vitamins. Why do dry cat foods need preservatives, you may ask? Spoiled food can be very dangerous, so it is important that dry cat foods contain adequate amounts of preservatives, which are a type of antioxidant, to prevent oxidation (spoilage).

Regardless of what preservative is in a cat food, always be sure to check its expiration date prior to feeding it to your pet. Aside from preservatives, other ingredients that you should look for in your cat’s food include 25 vitamins and minerals deemed essential by AAFCO.

What to avoid

We have already discussed what ingredients are important to have in a cat food. But which ingredients should you avoid? Again, cats do not need carbohydrates, which break down to sugars. Sugar has been linked to cancer in cats, so it is probably in your (and your cat’s) best interest to forgo foods that have carbs.

Cat experts recommend grain-free foods, or at the very least, those that contain only complex carbohydrates. Look for the words “corn,” “rice,” and “flour” to know which brands of cat food to avoid.

Other considerations

You may see distinctions like “natural” or “premium” when looking through dry cat foods. Healthy cat food does not have to have any of these labels, however, and sometimes those labels don’t mean much. Foods deemed “natural” might be labeled as such because they have no artificial ingredients. However, most cat foods do not have any artificial flavors anyways — but they do have man-made trace elements.

On the other hand, an “organic” pet food is one whose ingredients were grown and processed without pesticides. Dry cat foods advertised as “premium” do so without any FDA requirements for that label. Sometimes, a “premium” cat food is easier to digest.

You obviously want to feed your cat the very best food. Now that you’ve read this article, hopefully that task will be easier. Know that dry cat food doesn’t have to be unhealthy or contain grains, despite what some may believe. With your newfound knowledge, you can choose a healthy cat food to feed your furry friend(s)!

It's tempting to spend some time outside with your cat whenever the weather is nice, and taking your cat outside can give him a nice break from indoor-only life. If you love to spend time on your balcony, it's natural to consider letting your cat join you, but balconies can be dangerous for cats. In addition to the potential for a fall, balconies have several other risks that you might not be aware of. Understanding how to cat-proof a balcony can help you to make the space safer, so you and your cat can spend a little time outside together.

Will a cat jump off a balcony?
Balconies can be very dangerous for cats because of the possibility of "high-rise syndrome." Always Compassionate Veterinary Care explains that high-rise syndrome refers to the occurrence of cats falling out of high-rise buildings and needing veterinary treatment. The term originates when the Animal Medical Center in New York City treated more than 100 cats who fell out of high-rise windows. That occurred during just five months in the 1980s and highlights the fact that cats can and do fall out of high structures.

There are plenty of big and fluffy cats out there, but one of the best-known breeds fitting this description is the Maine Coon. These cats are not only impressive in size, but they also tend to have fantastic personalities that make them beloved family pets. While purebred Maine Coons are a little more uncommon in rescues and shelters, it's possible to adopt a Maine Coon mix that still has some of the breed's distinctive characteristics.

While telling exactly which breeds your cat is can be a little tricky, it's worth doing some investigative work to better understand your feline's background and what that might mean for the care he needs during his life.
Where do Maine Coon cats come from?
You may have heard that the Maine Coon Cate originated from a fantastical cross between a feline and a raccoon. Of course, this didn't really happen, but it could be where they get the name. (Another option, from a ship's captain who brought the first of these kitties ashore.)

If your cat throws up after eating grass, there's probably no reason to be concerned. Eating grass is a natural behavior for most cats, and throwing up after eating that grass also is pretty common. There are physical reasons for why your cat throws up grass, and aside from dealing with the inconvenience of having to clean up cat vomit in the house, this behavior usually isn't a problem.

But excessive vomiting and unusual grass consumption can be a cause for concern. If your cat likes to munch grass, then it's best to familiarize yourself with what's normal and what might be a reason to worry.
