Weruva Classic Cat Foods

Weruva Classic Cat Foods are made using high-quality ingredients like boneless, skinless white meat chicken and hand-flaked fish loins. With ingredients you can see, these recipes deliver hydration-focused nutrition that’s rich in protein and low in fat.

Specifically Formulated for Cat Health

Cats are obligate carnivores, which means they only need meat and water to survive. All Weruva recipes are formulated with this in mind. The calories in each recipe come from three places: protein, fat and carbohydrates. The calories from meat are comprised of protein and fat with minimal, if any, calories coming from carbohydrates.

Hydration Focused Recipes

Hydration through meat to meet the needs of your obligate carnivore. Weuva Classic Cat Recipes are all natural, with no grain, gluten, carrageenan, corn, wheat, or soy.

Human Food Standards

Weruva pet foods are made in a state-of-the-art human food facility that caters to many countries, each with its own processing standards. Weruva proudly earned an “A” grade on The British Retail Consortium (BRC), which is one of the strictest standards.

About Weruva

Weruva is a family company, wholly owned and operated by pet parents David and Stacie Forman since 2006. They originally developed Weruva, a luxurious natural pet food, for their three rescued cats: Webster, Rudi, and Vanessa.

Questions & Answers

5 Customer Questions


What is the protein, magnesium, phosphorous and ash percentages on a dry matter basis please?

Answer by ChewyOct 01, 2019
This variety contains 13.28% Protein content on an as fed basis (83.5% on a dry matter basis), 0.02% Magnesium content on an as fed basis (0.13% on a dry matter basis), 0.20% Phosphorus content on an as fed basis (1.26% on a dry matter basis) and 1.1% Ash content on an as fed basis (6.91% on a dry matter basis).

Has any laboratory analysis been done of this to determine the amount of mercury or other heavy metals are present? I'm concerned because of the prevalence of mercury in both mackerel and tuna.

Answer by ChewyFeb 23, 2022
Fish will have some level of mercury, and Weruva does test for mercury, histamines and polychlorinated biphenyl (PCB). Yet, not all fish were created equally. In a nutshell, the lower on the food chain, the younger and smaller the fish, the less mercury the fish will have. Weruva uses fish that meet the FDA’s list of those lower in mercury. There are many species of tuna, some of which have high levels of mercury; Weruva uses skipjack, a smaller and younger species that has lower levels.

What's the fat and carb content on an as fed and dry matter basis please?

Answer by ChewyOct 24, 2019
This variety contains 1.5% Fat as fed (9.4% dry matter) and 0.02% Carbohydrates as fed (0.1% dry matter).

What is the sodium content on a dry matter basis?

Answer by ChewyJan 27, 2021
This recipe contains 0.10% Sodium on an as fed basis and 0.61% Sodium on a dry matter basis.

My Cat Vomits after Eating her Fave Mack and Jack.

My cat loves Mack and jack, and she would not pretty much eat anything other than that flavor, but lately whenever I have opened the can (got through auto-ship)

My cat loves Mack and jack, and she would not pretty much eat anything other than that flavor, but lately whenever I have opened the can (got through auto-ship) for her, she refuses to eat it. If she absolutely has to eat it(given no alternative is provided) she vomits after a while. I thought that she was being picky, but the pattern went on. So I experimented and got a delivery from another pet store (same can, same weight) and she has no issue with it. I maintained the absolutely same storage directions as well. But I forgot to cancel my subscription, and I received a recent order. Opened the first can yesterday night, she vomited again. I have now surely cancelled the subscription, and won’t buy her food from Chewy again. I can’t even give this batch of food to the shelter in good conscience.

Tuna is the first ingredient not mackerel :(

Misleading and dissapointing that tuna is mixed into everything! "Pet owners should avoid feeding their pets a primary diet of fish-based foods to minimize mercury

Bandit is so picky - I've probably tried 20 different wet foods with her. Smokey eats anything lol! Bandit can tell the difference between the Mack & Jack in the 3 oz cans versus the 5oz cans. She prefers the 5 oz can. Just happy to have found her pleasure!

Is this normal? I’ve gotten mack and jack for years and never had bones in it before. This batch had a lot in every can. these bones are sharp and not soft. I am worried they would do serious damage. My cat had a couple bites before I noticed so I hope she’s okay.
