Questions & Answers

46 Customer Questions


What is phosphorus,ash,calcium? thank you


What is the source(s) of the “meat protein isolate”?

Answer by ChewyMar 27, 2019
Protein isolates are derived from a variety of food sources – plant, meat, dairy, and more. Protein isolates are typically 95+% pure protein, with some approaching 100% purity. Protein isolates are far from inexpensive byproducts. Unlike starches, they are distinctly not “filler” ingredients. Rather, they are the product of a focused attempt to extract the most valuable components out of a food source.

What size is the kibble?

Answer by ChewyNov 19, 2018
The kibble will be close to the size of a chickpea.

why is the 1st ingredient chicken meal and not chicken?? what is chicken meal comprised of? why does it contain ash and where does the ash come from?

Answer by ChewyJul 30, 2019
Chicken meals and byproducts consist of chicken meat, plus some of the bird's internal organs. As the liver is a good source of iron, these internal organs provide a highly digestible and readily absorbable source of some minerals.

Refuse to eat

Tried to get my cat to eat it because he was diagnosed just recently as a diabetic. Cat must eat before giving insulin shot and he refuses to eat it.

Great Food

This is a best kept secret. Not only is it starch free, but no other worthless things are added in. This is the only food other than raw either frozen or freeze

This is a best kept secret. Not only is it starch free, but no other worthless things are added in. This is the only food other than raw either frozen or freeze dried that my older girl can eat. Anything else and you will be cleaning up the floor and quickly as the other foods hit her stomach and return in a matter of minutes. She has a beautiful coat and stays in great shape on Epigen 90.

WARNING- Ultra High Phosphorous Levels

I discovered Wysong's Epigen 90 cat food and was feeding this option for years, after Dr. Elsey's added pork plasma to their dry food, causing my cats to vomit uncontrollably

I discovered Wysong's Epigen 90 cat food and was feeding this option for years, after Dr. Elsey's added pork plasma to their dry food, causing my cats to vomit uncontrollably. I wanted a high protein, low carb option, so I tried Dr. Elsey's. The Epigen 90 just was not right for them, and after a while, instead of remaining lean and energetic, like they did with the Dr. Elsey's low carb option, they gained weight and became extremely lethargic. I knew with a gut feeling that their food was making them like this, especially since they had vet visits recently. I changed them to the Wysong Restore, but after reading about how shady this company is in multiple reviews, I learned that the phosphorous and calcium levels could be contributing to some of their kidney symptoms, so I decided to reach out to the company, since the FDA REQUIRES a company to provide this information to the public. We should all have a right to know what is in the food we purchase for our cats, right? Exactly. So, when I reached out to Wysong, it was a complete joke. Their customer service rep told me they have no information at all about the Phosphorous levels, and that I could e-mail their technical support to ask if they have it. Technical support?! I e-mailed them a few times and they replied back to me just yesterday and their response was shocking. They said they have no information for me, and they don't recommend feeding on a percentage basis. This basically tells me the food has high Phosphorous levels, so be extremely careful with this, as it is dangerous to give high levels to any cat, especially aging cats. I am more than disappointed with this company and will never purchase their products again, as it could pose a real harm to my cats' health.

This company Wysong is amazing and so happy Chewy sells it ..I’ve been getting the dream treats for years my dogs love them and there super nutritious..my Bull dog Ruby has been suffering with colitis for months nothing from prescriptions to trying other dog food has helped ..I decided to try Wysong and although this brand of it is a little to rich the company thought for her ..they suggested the Adult Wysong and she’s been on it for about 2 weeks with great results little to no bleeding . I’m not making claim that this has cured her colitis but it sure has helped with her digestion. I’ll be ordering the adult and I’ll gift this Epigen to a rescue .very happy we’re on the way to happy tummy for Ruby

I love it because it's high protein and low in carbs, just what my cat needs. Amazing in that it's a dry kibble. I soak it in water to hydrate it so to be sure my kitty gets adequate moisture as in the wild prey meat and organs are mostly moisture.

Gave him diarrhea

What a mess...diarrhea all over the house. I was trying to find a non prescription dog food for my diabetic dog. This sounded good, but his poop never normalized

What a mess...diarrhea all over the house. I was trying to find a non prescription dog food for my diabetic dog. This sounded good, but his poop never normalized even though it was blended with the old food. At least now when he gets constipated I can give him some (a little) of this to resolve it.

Dry Food for Diabetic Cat

I got this for my newly diabetic cat so he can have a lunch snack while I'm away all day at work. He is quite picky but he does seem to like this food. It's fascinating

I got this for my newly diabetic cat so he can have a lunch snack while I'm away all day at work. He is quite picky but he does seem to like this food. It's fascinating that it is for dogs and cats. It is low carb.

My Kitty Lives

If it wasn't for this cat food I'd be expected to shell out $50+ for prescribed food for her. She has diabetes and getting her sugar and giving her insulin was awful

If it wasn't for this cat food I'd be expected to shell out $50+ for prescribed food for her. She has diabetes and getting her sugar and giving her insulin was awful for the both of us. She hated every aspect of it and my heart hurt with every fight we had. After starting her on this food, it took a few weeks, but finally her sugar is well controlled that she doesn't need insulin and I only have to check her sugar every so often. Before, I was genuinely considering if putting her down was better than fighting with her since her quality of life was so affected, but now? She's alive and well.

Great low carb option for diabetic cats

All of my 10 cats eat this. Follow the instructions on introducing it though. It will cause some GI upset if only feeding this.
