What's the function of Menadione Sodium Bisulfite? I heard that it is toxic to cats, it that true?

Answer by ChewyJun 26, 2018
Menadione is a vitamin. It is the man-made version of an essential nutrient commonly known as vitamin K3. This is not toxic to cats.

Are you considering sticking a larger bag? I already purchase the chicken version and I would love to give this a shot for rotational feeding, but I would really like a larger bag like the 10 pound chicken.

Answer by ChewyDec 30, 2019
At this time, this formula is only available in a 4-pound bag.

What is the ash % and the carb %?

Answer by ChewySep 17, 2018
The Ash content is 7.5% as fed and 8.33% dry matter basis. The Carbohydrate content is approximately 15%.

How many cups in a 4 lb bag?

Answer by ChewyMar 12, 2020
There are approximately 16-pounds of food in the 4-pound bag.

I’m not a big kibble feeder, but this one is my favorite

I’m not a fan of feeding kibble to felines, but of all the ones out there this one is pretty great for the price. My kitten loves it (it’s rated for all life stages)

I’m not a fan of feeding kibble to felines, but of all the ones out there this one is pretty great for the price. My kitten loves it (it’s rated for all life stages) and I don’t feel as bad when I have to feed him a little kibble with this food.

Change in kibble

Instinct stopped producing the duck kibble my cat liked. Finally got him to eat this food and on my second bag discovered they had changed kibble size and color

Instinct stopped producing the duck kibble my cat liked. Finally got him to eat this food and on my second bag discovered they had changed kibble size and color (I assume something else) my cat will no longer eat it. Not a Chewy problem but why keep changing especially for our known finicky friends.

Used to be a great food

Changed the ingredients and now canola oil is the 6th ingredient. Now my ferrets refuse to eat this garbage. It was such a great food for years for them. I would’ve

Changed the ingredients and now canola oil is the 6th ingredient. Now my ferrets refuse to eat this garbage. It was such a great food for years for them. I would’ve loved for them to raise the price instead of changing their formula completely. Absolutely disgusting of the company to change it in secret as well.

Very expensive for a cat food it cost me $ 54 no free shipping

I've used Instinct products for years because of their high protein.

I try to alternate this with the chicken version of Ultimate Protein. I also feed Instinct wet.

The healthy ingredients, more protein and less filler equals healthier diet

Our cats gobble it up. Because of the protein, they eat less and stay full longer. Also, their bodies make better use of the food source making for less waste

This cat foodIs great !

Limited ingredients was helpful to Identify my cats allergies. Unfortunately duck is one of them so this food won’t work for the intended feline but his sister devours
