Questions & Answers

Why does the color of the food vary from bag to bag?

Answer by ChewyJan 06, 2026
Color variation can be seen on occasion due to the raw materials used, as no artificial dyes or colors are used. The color variance will not have an impact on the nutritional quality and safety of the kibbles and will not be harmful to the pet.

Greatly improved my cat's health

My 19-year-old cat was recently diagnosed with kidney disease after rapidly declining in health. I normally have reservations about prescription diets, and while the ingredients aren't what I would typically choose, there is nothing else on the market with the same nutrient analysis that supports kidney function. My vet gave me a sample, and I wasn't even able to gradually transition her off of her old food because she refused it and begged for this food. It is almost a miracle the difference in her health and energy after just one bag, and she gained all the weight back she lost before switching foods. Before starting this food, I thought it was time to say goodbye, but now she's energetic and spunky, and most people don't believe her age. The hydrolyzed protein is supposed to be easy to digest and better for cats with food sensitivities as the immune system doesn't detect it the same way as other protein, according to my vet. While this may be part of what's helping, my cat still chronically vomits, requiring an antiemetic medication, but maybe other cats would have more benefit.

This has been great for my cats. They didn’t hesitate to eat it at all. The feeding measurements are in an annoying size (who makes a 5/8 cup measurement?). I transitioned them too quickly and was unaware that this food is notorious for causing GI upset the first 2-3 weeks. I like this for my cats because one has IBD and the other has CKD so this is formulated for both of their needs and I don’t have to worry about figuring out how to train them to eat out of separate bowls.

My bag of dry cat food was not packed in a box. All they did was put a label on the bag itself and shipped. At any point in shipping the bag could have been punctured and contaminated. It was bad enough I had to clean the outside of the bag from the dust from shipping before taking in the house. This is the first time my shipment was not in a box

Small flavorful kibble for renal support

My Senior cat Ringo loves this kibble. He has been diagnosed with kidney disease and must be on a renal diet. He has this and Royal Canin renal support E canned

My Senior cat Ringo loves this kibble. He has been diagnosed with kidney disease and must be on a renal diet. He has this and Royal Canin renal support E canned pate 5.1 oz that is his strict diet. I've noticed a big improvement in his health overall since starting him on this food which is mostly the wet canned food in addition to the kibble which I leave out for him to have at his pleasure. . I don't give him anything else but this due to his health. Ringo prefers this over the Hills that the vet recommended.

I was very skeptical about this as the track record for my senior girl in regards to prescription diet food has been horrible. I was over the moon happy when I heard her crunching away on this new dry prescription food.

I have a 14 year old Maine Coon mis with kidney disease, heart disease, and intestinal issues. His vet and cardiologist recommended this food for him and he’s doing AMAZING on it. He’s completely stopped vomiting and has been peeing in his box again. It is a very expensive food, but it is prolonging and significantly improving Willoughby’s quality of life. Worth every penny.

I was surprised that my picky eater cat likes this food. She eats it every day. I am so happy because she needed to gain some weight and she has already gained a little, just eating it for a couple of weeks now. She doesn't throw up, has good bms, and I could not be more pleased.
