    Buyer’s Guide

    Reading Labels

    Not all companies are out to trick consumers with the way that their labels are worded. However, it is still something that you should watch out for when buying cat food.

    If it says that the food contains “beef,” “chicken,” or “tuna,” or something similar, then it must contain 95% of the specified meat. This rule is per the guidelines set by the Association of American Feed Control Officials (AAFCO).

    Labels that use the modifiers “dinner” or “buffet” signifies that at least 25% of the total weight of ingredients has to be the specified meat.

    Finally, any phrase that includes the word “with” as it describes the ingredients, i.e. “with beef,” is only required to contain 3% of that meat.

    If you want to know even more about guidelines, packaging regulations, and specific terms, look to the AAFCO. You can learn what unfamiliar terms mean, what could be harmful, and what is not.

    Some things, taurine as an example, may sound like harmful chemicals. But in fact, taurine is an amino acid that is found in animal protein. Cats need it for essential organs to function correctly, such as their brain, vision, and heart.

    Ingredients to Avoid

    Certain foods contain unhealthy ingredients for cats. Some of these are somewhat controversial. For example, some people do not agree with grain-based diets, including corn or wheat, for animals like cats and dogs. Others say that they provide necessary compounds for their health.

    Depending on your cat’s age and state of health, you might be able to get away with offering them more of these foods if you feel comfortable with it. If you are on a mission to serve dishes that are as healthy as possible, keep an eye out for these ingredients:

    • Butylated hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT)
      • BHA and BHT are both nasty chemicals used as artificial preservatives in all kinds of food, both human and animal. They have been reasonably found to be human carcinogens and have caused tumors in lab animals. A little of either of these won’t harm your cat in the short term, but eating it every day can have deteriorating effects as they age.
    • Ethoxyquin
      • This is another chemical preservative that is now illegal to use in human food in the U.S. but is still legal in animal food. It is harmful both if swallowed and if it comes into contact with the skin. It can be tricky and is not often shown on ingredient labels because it mostly turns up in the fish meal.
    • Garlic
      • Garlic is extremely toxic to cats. The idea behind adding it into some cat foods is that it can reap beneficial effects in low doses. However, this hasn’t been entirely proven correct, although the harms have been.
    • Wheat and Corn Gluten
      • Wheat and corn gluten are more filler than anything, at least in animal food. Wheat gluten has become a popular addition to vegan’s diets because it has high protein content and is “meat-like.” It shouldn’t be in cat food, though, since it is a way to raise crude protein numbers with a low-quality meat substitute.
    • Carrageenan
      • Another controversial ingredient, carrageenan, is red seaweed. Producers use it as a thickening agent. A specific kind, named degraded carrageenan, is thought to be a carcinogen. It is not allowed for use in any food. However, some believe that it might become degraded after cats ingest it and pass it through their stomach acid.
    • Caramel
      • Coloring in a cat’s food is entirely unnecessary because the cat doesn’t care what color their food is. It is an unnecessary addition, and some options, including caramel, have been proven potential carcinogens.
    • Propylene Glycol (PG)
      • All kinds of things go into pet food to give it the distinctive traits that pet owners expect it to have. PG is a moistening agent to obtain the “right” texture in food and treats. It is derived from the chemical compound in antifreeze and can be extremely toxic.
    • Meat By-Products
      • When a company claims to use “meat by-products,” it is saying that it comes from low-quality sources, such as dead animals from farms and ranches, fats, and food waste from restaurants.
    • Food Dyes
      • Other than a caramel color, food dyes can include Blue 2, Red 40, and Yellows 5 and 6. These have been linked to many different kinds of allergic reactions and some cancers in humans and animals.
    • Glucose
      • Glucose is sugar. Cats do not need any sugar added into their diet, including dextrose. It often leads to obesity and possibly even diabetes.
    • Sodium Nitrite
      • Sodium nitrite, when it enters into a cat’s body, becomes a carcinogen. It is often used as a color and flavor enhancer for meats.

    Ingredients Cats Need

    A cat’s diet is quite straightforward. Naturally, they are carnivorous and need mostly pure proteins in their food. Today, since pet owners mostly buy their food, preservatives, fillers, and unstandardized “extras” can make their way into a cat’s diet. Watch out for these things as you search for the best food for your pet.

    • Standardized Protein Sources 

    Protein doesn’t always come from a pure source. Budget brands often look for things like wheat gluten to increase protein without increasing costs. However, it doesn’t mean that it is healthy for your cat.

    Look for foods that don’t list their protein source as anything other than “meat,” such as “meat derivatives” or “meat by-products.” You can keep an eye out for meats and organs, such as chicken liver or heart.

    • Named Fats

    Cats need high-fat content to meet the required 20-24% of fat in their diet. Some owners might think that high-fat content leads to obesity, like it might in humans. However, look for named fat sources, like chicken fat, for a healthy addition to your pet’s diet.

    • Carbohydrates Sans Fillers

    Carbohydrates mean more energy for cats. However, since they are natural carnivores, they can have issues digesting them in high concentrations. They do not have any need for carbohydrates from grains, and these can end up triggering allergies. Most carbohydrates act as fillers in cat food. Avoid these potential issues by finding foods with carbohydrates like potatoes or peas.

    Cats can be extremely finicky eaters, but finding them the healthiest options is essential. Learning to read labels is necessary to determine if a food is as healthy as it claims to be.

    Watch out for divisive labeling techniques and familiarize yourself with the terms that brands are allowed to use. Some of them can be somewhat misleading. Knowing what your cat is getting in each dish will help both of you.
