Why do they state "starch free" when potato isolate is a starch?
Answer by ChewyOct 10, 2018
Potato protein isolate is not a starch, but a pure by-product of potato processing. Potato starch is another by-product of potato processing, but it is drastically different from and not present in potato protein.

What is the sugar content? Is there one with no sugar for diabetic cats?
Answer by ChewyJul 17, 2019
Epigen™ is formulated with high meat and fat content (60% protein, 15% fat minimum), and contains no added, simple sugars. Due to your pet's diagnosed condition, we recommend consulting your Veterinarian to see what would be a good fit for your pet's current treatment plan.

What is meat protein isolate? Sounds skechy...
Answer by ChewyDec 13, 2017
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, and their price/cost reflects that.

What is the kcal per cup of this food? I can't seem to find it here or on their website.
Answer by ChewyFeb 10, 2018
This formula has approximately 489 calories per cup.

Won’t touch it

I’m extremely disappointed, I wanted to go for a higher grade quality of food for my girl. But she just will not touch it. I try to put in a couple pieces of other food to entice her, she simply will take those pieces out and not touch it at all. This is been going on for two days now. My girl needs to eat!!!

Nutritional but not palatable

Everything is the ingredient list and details describes a great dry food formula for my cat. However, tried many times and tricks, he attempts to eat it, but spits it out. He leaves the pellets gummy and sticky all over the kitchen floor.

Palatability lacking

I’m sure it’s good metrically (ie ingredients, macros) but my cats refused to eat it. They said it was dry and tasteless like cardboard. Maybe they are spoiled with flavor enhancers in other foods but even when mixed with American Journey dry, they consistently avoid individual kibbles of this food. Sad panda.

Opened bag and cats went crazy jockeying for control of the bowl had to give two bowls. Left the canned food they gobble up. Good stuff will switch everybody

This works for the upset tummy

My cat has been having tummy problems for months, everything tried by the Vet and me wasn't working. I really thought it was the food in some way, but the Vet wasn't sure. After months of soft, stinky poo, poopy butt, and vomiting, plus all of the Vets suggestions, tests, and visits. I took her off from all cat canned food and started feeding her canned chicken breast, this helped a lot but not completely. Then I switched her dry food to Wysong Epigen Starch Free GF, and she got better, gained weight, and I got to stop cleaning up spots in the house and her butt. We can also stand to be by her now, because the gas and extreme farts are gone. We are all so much happier!

Both cat and dog approved

I have a 3 year old picky Boston terrier and she was apprehensive but eats it as well as our cat who immediately went to it!

hope it gets better

I’m trying this out to hopefully have a less expensive dry food than Dr. Elsies, which is great. And the cats like Dr. Elsies. They will eat this, but they are not super fond of it. I gradually introduced it to them over the course of the week. They still get wet food in the morning.

Weight Loss

He's 20lbs. and only 5 years old. My fault. I never want another diabetic cat so have been researching dry food (which he loves) that is more protein and less carbs. He's been eating Blue Buffalo Trim & Healthy and loves it. But it's too low in protein. So I bought the Wysong and he at the first bowl fine. Then he balked. I have been mixing it with the BB and slowly he's eating it but reluctantly.

My cat says no way

Maybe its a good product but my cat would not touch it - she tried a little bit and then refused to continue to eat. I left it in the bowl and refreshed it for week and never would she eat it if she was starving. I should have know when it said either dog or cat- that doesn't even sound right . A cat and a dog are two different things

Tasty and Nutritious

I had been on the search for quality kibble that was more biologically appropriate for cats, and finally settled on this one, which has an awesome formula. And a bonus, both of my cats loved it from the start. I highly recommend.
