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 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.

Kitties liked initially

My old man 18 year old Rag doll developed diabetes, so I had to change to a low carb formula. Of the three kitties in the household, they all initially ate this food, but now only the diabetic kitty will eat it, because it's the only kibble I allow him to have. Probably will switch to another brand when this is gone.

We are both pleased!

A year ago I noticed my cat was getting pretty chubby. This kibble was highly recommended on a few sites I looked into and so I decided to try it. I see a lot of people mentioned their kitties either had upset tummies or wouldn't touch it but my boy loved it! We introduced very slowly and he is always excited for food time. This kibble(paired with about 1/3 his diet being tiki cat wet food) has my cat a healthy weight, shiny coat, and tons of energy. Highly suggest giving it a try.

My cat stopped begging

My cat was very food insecure and would constantly beg for food and eat more than she needed and gained weight. I needed a food I could leave out when I work long days without her overeating. This worked great. It's not her favorite by any means, but she will eat it when she's actually hungry. No more begging and she lost weight!

good stuff, in small quanity

the ferret rescue recommended this food added in small quantity to the regular kibble, because it is high in protein and the ferrets are really benefited by it, but it is something that most cannot eat alone, because it can cause diarrhea for most, if feed solely. So I mix one cup of this, to four cups of kibble, and my little war weasel loves it!

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.

My cat doesn't like it...

Great ingredients list, unfortunately my cat would rather miss his kibble meals than eat this product.
