Frequently Asked Questions

What makes Nutra Bites different from other cat treats?

Some commercial cat treats are filled with unhealthy ingredients (like wheat flour and corn syrup), low-quality protein sources (like meat by-products), or fillers (like corn and rice).

Nutra Bites makes sure to keep all those things out — because there’s simply no need for them. Not only is top-grade, nutrient-rich chicken liver the main ingredient, it’s the only ingredient.

How can Nutra Bites help my cat?

Nutra Bites are low in calories compared to many other cat treats, so they can help your cat maintain a healthy weight. They can also spare your cat of potentially-harmful additives and fillers.

Chicken liver is also rich in vitamin A, vitamin B, iron, copper, taurine, phosphorus, zinc, and essential fatty acids to support your cat’s digestion and overall health.

Does my cat need Nutra Bites?

Nutra Bites are an incredible tool for positive reinforcement, rewards, or simply treating your cat. Cats of all shapes, sizes, and ages can benefit from this low-calorie, nutrient-dense treat.

These treats can also support healthy digestion — so if your cat has ever had digestive issues, these treats could be especially beneficial for them.

How pure are Nutra Bites?

Nutra Bites are made with one ingredient: Quality chicken liver. To ensure their purity, all of our products go through rigorous testing for quality and potency at an independent, 3rd-party facility.

What if my cat doesn’t like Nutra Bites?

Nutra Bites are made with 100% freeze-dried chicken liver, which your cat will go crazy for. But if for any reason you (and your cat) aren’t completely thrilled with Nutra Bites, simply contact our customer service team within 90 days of your purchase, and we’ll refund your purchase price — no hassle, no stress.

Is chicken liver better than beef liver?

Chicken liver has generally higher nutrient content than beef liver. It’s also leaner and much lower in calories. Therefore, it can be effective for helping your pet stay slim and trim.

Best treats ever

Pet's Name: Dax and Seven

Pet's Age: 4 years

“The two kitties are very interested in these treats--especially when a new bag is opened! Sometimes they decide they are bored with their wet food (no matter how good it is for them) so I put Nutra Bites treats on top of their bowl to pique their interest. It works like a charm, and I feel good about feeding them treats that have a single ingredient--just protein. When I get to the bottom of the bag and there are only crumbs left, I add a little water to them to make a paste, and mix it into their wet food. No waste!”

Pet's Name: Tigger

Pet's Age: 10 years

“So far Tigger really likes these chicken liver bites. I give him a small (4 or 5) amount in the morning as an appetizer before I give him his usual breakfast. He knows where I keep them and he heads right for them. I will continue to give him this treat. KF from CA”

Nutra Bites & Feline Renew

Pet's Name: Dusty

Pet's Age: 13

“Nutra Bites are a great snack. I also use it as a topping for regular food because Dusty is sometimes a finicky eater and it gets her started on her food. The chunks are rather large for her so I break them up first. As for Feline Renew, it is very thick and oily. Dusty got more on her face than in her mouth. I suggest mixing it with food. I also use Nutra Thrive. All are great supplements that are helping enrich my 13 year old cat’s life.”
