Things to consider before buying cat food

Choosing a cat food can be a difficult process. There are lots of brands, flavours and forms. Manufacturers use opaque words to describe the ingredients, and what do cats actually want from a food anyway?

“You are what you eat” is just as true for cats as for people. Choosing the right food will help keep your cat happy and healthy without hurting the environment or your wallet!

At YourPetProfessional we use a unique algorithm to assess foods based on their suitability. Our algorithm rates how well they meet cats’ nutritional requirements, the quality of the ingredients and palatability. We also rate products on price and sustainability.

The ideal food should be high in protein, have a moderate level of fat and low carbohydrates. Most of the protein should come from animal sources. It should be free of artificial preservatives and low in ingredients which could potentially harm your cat. There should be no “filler” ingredients.

When we discuss the cost of a food we take into account both the price and how calorie dense it is. This way you can get an idea of a food’s cost-per-day allowing you to compare apples with apples.

Sustainability is a rough measure of the food’s impact on the environment. Sustainable foods complement the human food chain rather than competing with it. They include high-quality, nutritious ingredients that cats love, but simply don’t fit with modern appetites. Sustainable foods use low-impact sources of animal protein.

Our recommendations will suit the vast majority of cats, but if your cat doesn’t seem to be doing well on a particular food you should always seek veterinary advice. If your cat has a specific health problem consult our guides here and your veterinarian for advice.

Under The Sun Cat Food Review

Under The Sun is a Canidae brand. Canidae was founded in 1996 in California.

Under The Sun is not manufactured in Canidae’s own facilities. The food production is outsourced, largely to Diamond Pet Food.

Canidae is aiming to grow the ingredients for its food through its Canidae Farms Initiative. However, the majority of ingredients are bought in. 

Under The Sun cat foods contain protein from meat, meat/fish meal and plant protein. Meat/fish meal is a high quality, nutrient dense ingredient. These sources are healthy for cats, because most protein needs to come from meat.

Fish meal main ingredientHigh levels of filler ingredients
Fat from animal sourcesLow protein
Relatively affordableVery high carbs

Most recipes contain fish
Under The Sun Wet ProsUnder The Sun Wet Cons

Under The Sun Dry Food Nutritional Analysis (Dry Matter)
Under The Sun Wet Food Nutritional Analysis (Dry Matter)


Protein is a key part of a cat’s diet and is required for all aspects of health. A protein level of 40% is needed to maintain muscle mass.

Under The Sun’s dry foods contain 33% protein, the wet foods are 50% by dry matter. This means that if you choose to feed Under The Sun’s dry food you will need to supplement with wet food to help to ensure your cat maintains their muscular strength and activity level.


There is a lot of controversy about whether cats need carbohydrates and if carbohydrates should be in cat food. Cats can absorb small amounts of carbohydrates, but too much can cause an upset tummy.

Under The Sun’s dry foods contain a very high level of carbs. This level of carbs may cause digestive upset, and will not give your cat any benefit. Less carbs would allow you to feed less to get the same benefit.

Under The Sun’s wet foods contain a moderate level of carbs. However this level of carbs is higher than average for a wet food.

Ingredient analysis


Animal protein makes up the majority of the protein in the wet foods. Cats cannot produce taurine or arachidonic acid. These are two of the essential building blocks of protein which are only found in meat. The high proportion of animal protein in these foods will more than adequately provide these essential nutrients and keep your cats healthy.

Quality animal protein sources like those seen in this food are palatable to cats. This means your cat is likely to enjoy the taste. However, online reviews are mixed with a number of owners noting that their cat refused to eat this food.

The main ingredients in the wet foods are high quality, this means that you aren’t paying for fillers that do not benefit your cat.

The dry foods contain fish meal. This is a nutrient dense food, which means that a little goes a long way.

The fat in Under The Sun foods comes primarily from animal sources which is a good thing.

Under The Sun’s foods rate slightly above average on our sustainability criteria. Meat by-products are present in these foods, see here for why food should contain by-products. The ingredients in these foods do not compete with the human food chain. Ingredients are also sourced locally.


Under The Sun’s dry foods contain high levels of filler ingredients. The second and third ingredients are plant based sources of protein. However, these foods do contain several “meal” products which partially offsets this.

Under The Sun’s dry foods are high in cabohydrates and low in protein. For this reason we cannot recommend feeding them alone. High carbohydrates can cause stomach upset and low protein means your cat could struggle to maintain their muscles.

Most foods in the Under The Sun range contain fish. Feeding foods with fish could increase the risk of certain health conditions in your cat. We would recommend avoiding, or feeding less of, the products in this range containing fish.

Under The Sun’s wet foods are a reasonable quality food for your cat. They are have high protein levels and moderate carbohydrates. The ingredients are high quality. Howevver, these foods do have higher than average carbohydrates for a wet food.

Under The Sun’s wet foods have above average sustainability, they utilise by-products which is a good thing.

Under The Sun’s wet foods have a lower calorie density than most foods, which means you will need to feed more of them. This makes them less good value.
