About Diamond Naturals Dry Cat Food

Uncompromising Holistic Nutrition

Diamond Naturals dog food provides high-quality holistic formulas designed to meet every pet's needs. These nutritious recipes are enhanced with proprietary probiotics for good digestion and immune system support, and superfoods are added to supply nutrients that keep animals strong and healthy.

Superfoods That Deliver

They didn't just add a few superfoods here and there in Diamond Naturals. You'll find 10-20% superfoods in all Diamond Naturals dry foods, made up of tasty ingredients like kale, blueberries, chia seeds, pumpkin, quinoa, papaya, carrots, kelp, coconut and spinach.

Balanced Digestive Support

Foods with added probiotics allow more nutrients to be absorbed and used by your pet's body, and that leads to better digestion and overall health. Diamond Naturals foods are enhanced with patented Viables probiotics. Prebiotic fiber from chicory root plus soluble and insoluble fibers from pumpkin, coconut and dried kelp give extra digestive support.

Really Delicious Real Proteins

Made with real chicken and fish meal, Diamond Naturals cat foods satisfy carnivorous cravings meal after meal. These nutritious animal proteins have the essential amino acids your kitties need to keep running, playing, pouncing and staying fit. High-quality proteins like these are the building blocks of healthy muscles and strong bones.

No Corn, Wheat or Soy

All of Diamond Naturals' recipes exclude corn, wheat and soy, common fillers that are used in pet foods. If your cat is sensitive to this trio of ingredients, there's no need to worry when feeding Diamond Naturals. Instead you'll find whole grain complex carbs like cracked pearled barley and quinoa for lasting energy.

Questions & Answers

17 Customer Questions

Why is there powdered cellulose in this food? It is not a food product?
Answer by ChewyNov 01, 2018
A plant-based fiber, Cellulose helps plants defy gravity. And, it helps bind the ingredients helping make the product into pieces or a chew. 

Is this cat food good for senior cats?
Answer by ChewyAug 02, 2018
Diamond Naturals Indoor Cat Chicken & Rice Formula is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for maintenance. It is ideal for everyday feeding for adult cats.

Is this hairball control as well ?
Answer by ChewySep 28, 2018
This formula contains added insoluble fiber to help control hairballs. It is also nutrient-rich and highly digestible with prebiotic fiber to help support your cat’s digestive health.

Does any diamond naturals ingredients come from China??
Answer by ChewyOct 03, 2019
Diamond Naturals uses the highest quality ingredients and manufactured in America in state-of-the-art facilities. This formula uses some ingredients that are not USA sourced, like flaxseed and barley, both which originate in Canada and dried chicory root from Belgium. There are ingredients such as folic acid and taurine that can only be sourced out of China.

Changed Formula

We've been using this food for at least 4 years, recently something has changed and now the last 4 bags we've received all the cats (12) will not touch it. Chewy already replaced one bag at no cost, because I thought maybe it was damaged or stale or something, but nope, its been consistently disapproved by the furry overlords. Disappointed, as this was a great product previously.

Fed the strays and ferals

I really wanted this to work out for my cats. They tolerated it, yet one of them was throwing it up every time. She's never done this with any other food and is a good eater. She eats everything so I was very surprised this disagreed with her tummy. I fed about 50 cats twice a week so I mixed it into their food.

Fantastic Dry Food, high quality plus

Both my Cats were rescued from bad situations,so when I got them they were skinny, poor coat and unhealthy. After many trials and errors my Cats were thriving on Diamond Naturals Indoor Chicken formula. They gained weight, thick, plush coats followed and best of all they were happy, healthy and playing a lot. My Cats are picky eaters, but they love this, and purr with happiness all the time. Amazing transformation thanks to Diamond Naturals Indoor Chicken and Rice formula.

Alternate food

Had to find alternate catfood.The Blue Buffalo they had been eating for last 5 years was discontinued and they added tastefuls instead which my cats detest.My catfood started costing me a 120 dollars a month because of increase in feral cats in the neigborhood.So I tried diamond natural because my two dogs have enjoyed this brand for 5 years.It is comparable to blue Buffalo but way less cheaper and bigger amounts and they seem to like it as much as the old brand of blue buffalo.It has a slight decrease in protein which is subliminal and effects nothing.

My cats didn’t like it, gave it to outdoor cats

I attempted to mix a small portion of this cat food with my cats' previous food, but surprisingly, they consistently left the new food behind. As a result, I ended up giving it to the outdoor cats.

cat loves it

I was previously feeding Canidae Healthy weight tuna to my three cats. One of the three was overweight so I was trying to slim her down. They’ve been on it for a few months now and I noticed the “fat” cat had significantly lost weight at first I was glad but then I realized she was underweight. I checked the calories and they’re extremely low and the food is kind of pricey. I decided to switch to diamond naturals because I have three cats and I needed a food more affordable and something that would put weight back on her. Today I mixed the diamond naturals in with her current canidae to start the switch and she picked out all of the diamond naturals and ate every single last piece of it. I’m so happy she loves it and so glad she is eating her food again.

I’ve fed this food to my hedgies for many many years and they always do great on it! (Cat food is better for hedgies vs hedgehog food!)

Fingers Crossed!

I am desperately trying to find a food that works as well as the Royal Canin Gastrointestinal, due to expense and unavailability. My cats are super picky and have issues with vomiting and constipation. I researched and found this food. I have been mixing it in with what I have, and they expertly eat every piece of the other food leaving all of this in their bowl. I do not understand why they wont eat it. In the food's defense, they wont even eat salmon! I will keep trying. I think they are accidentally eating some as time goes by, and there has not been any vomiting and the stools look more "normal". Still keeping my fingers crossed. The ingredients are good and it is a great value! Half of what the RC costs and more than twice the amount in the bag.

Nala approved!

I feed both my cat and dog diamond naturals and I have no complaints. They both have soft fur and healthy digestive systems. I appreciate the probiotics and superfood in this blend.

Very Happy with This Food

Switched to this food due to possible corn allergies of previous food. Cats were throwing up regularly with that food (hairballs and no hairballs). This food, with Ground Miscanthus Grass replacing previously used cellulose, is an excellent choice now. I never felt comfortable feeding animals cellulose.
