Why is there no tuarine in this on ingredients list? It’s one of the 5 needed ingredients a cat must have.
Answer by ChewyJul 26, 2020
This cat food contains 0.1% Taurine content on an as fed basis, minimum. This formula does not contain synthetically added taurine within the ingredients. Taurine is found naturally within meat, with the level varying depending on the type of meat.

How about hairball control?

My babies love it

Some people feel this isn't the best brand. I feel this is an excellent brand. My cats are very picky and took to this right away. Affordable pricing for big bags. Small pieces. No artificial dyes. I love it.

Must Not Taste Good

I thought the price was excellent for a 40lb bag, I buy cat food for the strays in my neighborhood & my own cats (I have 5), But none of the cats will eat it! I can only surmise that it doesn’t taste good to them. They’re use to cheap dry food like Kit n’ Kaboodle but I bought this because I know Diamond is an excellent brand! I am so surprised & disappointed with this discovery. I been having to mix it in with the cheap dry food or in their wet food just so I can get rid of it since I don’t think a shelter will accept an opened bag. I hate giving bad reviews but I’m just being honest.

Picky eater approves!

I’m not sure why so many had issues with this food. I have one who’s picky and another who throws up almost all foods. Both took to it right away and no tummy issues! We have 5 cats total and it’s been a hit with them all!

Diamond 40lb maintenance cat food

I have taken on feeding quite a few extra kitties on my property, this seems to be the best value and quality. Only issues as of lately is past few bags have come to me torn open for some reason. Of course Chewy has made it right.

Bigger &better

My cats like it so I do too. I've tried most foods on the market. This food keeps them shiny,healthy and happy. I do wish it came in a resealable bag and was easier to open.

My cats love this

I switched my 8 cats to this grain free cat maintenance. I have noticed their coats are more shiner and more energetic.

Didn’t care for it

A vet tech told me this is what she feeds her cats, so thought I’d try it as add-on with mine. My two cats (ages 21 mos.) didn’t care for it. I mixed it gradually with their current food. So, I’ve been putting a couple of scoops outside at night for the ferals and outdoor pets that roam the neighborhood. It’s not going to waste!

Cats really wanted.

I needed a easy way to get cat food because traveling isn't something that I do a lot anymore.

Barn Cats Do Well On This

Been feeding this for a year now to my outdoor house cats and my barn cats. Their coats are shiny and they look really healthy. They eat it up and the ingredients are very good. You can't beat the value of this maintenance cat food.

Love this food!

My growing German Shepherd was ALWAYS hungry! No matter what I did she was constantly hungry. I switched to this food and within days she was satisfied after her meals. She loves the flavor and eats everything right up. Her coat is very shiny and her weight is wonderful!
