About Cat Mix

This is a high quality pet supplement for cats that provides nutritional support to help keep your pet healthy.

Cats have their own nutritional needs to suit their systems, especially since they are carnivorous.

With this comes many other dietary needs that may not be met by cat food alone.

Supplementing your cat’s diet helps ensure that they’re getting enough vital nutrients to maintain overall health.

If you’re concerned that your cat may not be getting enough essential nutrients from diet alone, Cat Mix can help.

What factors do we use to rank supplements?

What should you look for when picking the best supplement for cats?

Here are factors you should consider, and the factors we use to rank too!

1 – Price = What’s the price of the supplement? What’s the cost per serving?

At Eating Enlightenment we value quality over price. However, all else being equal, then price comes into consideration. 

2 – Reviews = How many reviews for each product? What’s the average rating? How many third party reviews?

We strongly believe in third party reviews. Many supplement companies list positive reviews on their website, but third party reviews include negative comments. We always go with third party reviews.

3 – Reputation = How reputable is the brand behind the supplement? How long has the brand been around? What’s their mission? 

We believe that a company’s intention is highly important and should be one of your top purchasing decision factors.

4 – Taste / Absorption = What’s the taste? How quickly does your body absorb the supplement? Do reviews mention any negative side effects like an upset stomach?

5 – Perceived Therapeutic Effect = What beneficial effects or feelings does this supplement promote?

6 – Food Allergens = Does the company provide allergen info?

7 – Science / Certifications = Does the company list transparent scientific studies on their website? Do third party certifications test the company’s supplement for quality control? How many certifications does the company have?

8 – Pros/Cons = What are the pros and cons of each supplement? How is the supplement unique? For what situations is this supplement best?

Which cats benefit most from supplements?

There are certain cats that may benefit more from cat supplements than others. These groups include:

  • Cats with rough skin and spotty fur: This is usually a sign of poor nutrition and a lack of essential fatty acids and nutrients in the diet. Supplements can help to correct this by providing the necessary vitamins and minerals.
  • Cats whose hearts are failing and cannot jump or be active anymore: Senior cats can benefit from vitamins and supplements.
  • Digestive health is poor: Cats who struggle to digest food can benefit from the paté which is easy to digest.
  • Cats with joint problems: Joint problems are often caused by inflammation and a lack of important nutrients such as omega-fatty acids.
  • Cat’s immune system is constantly under attack, your cat is sick very often.

When should cats take supplements?

The most important thing for cat supplementation is taking their supplements with food. Cat owners need not worry about the precise time, “when” does not matter so much. 

Which cats may not benefit from supplements?

Not all cats will benefit equally from cat vitamins. Certain supplements may not be safe for pregnant or nursing cats, so it’s best to check with a vet first in these cases. Kittens under six months old should also not be given cat vitamins and supplements unless directed by a professional.

How to get your cat to take their supplements?

Some cat owners like to use food foils or pill pockets to hide the supplement in. You can also try to wrap the supplement in something that your cat enjoys eating, such as a piece of salmon or chicken.

Tablets and capsules:

If your cat is resistant to taking tablets or capsules, you can try opening the tablets or capsules and mixing the contents with a bit of wet food. Some people find that their cats are more likely to eat these if they are in small pieces.

Liquid supplements:

Many liquid supplements come with a dropper or pump top, which makes it easy to add the correct amount to your cat’s food. If you are using a powder supplement, make sure to mix it well.

Food foils and pill pockets:

If you are using food foils or pill pockets, you can try hiding the supplement in your cat’s favorite wet food. Some people find that their cats are more likely to eat these if they are in small pieces.

Food sources for cat nutrition

While pet food is good, there are a few other food sources for great cat nutrition.

Fish obviously is one idea. Cats love fish! Of course milk is a great treat for cats too.

Generally speaking cat food is good for cats too. However, please take care to buy products made in the USA so you can be assured of high quality.
