Felix KnabberMix Review: The Surprisingly Addictive Cat Treat Mix Owners Swear By

You open a bag of cat treats, shake it hopefully, and your cat gives you that look. The "nice try, human" look. A half-hearted sniff, maybe one polite bite, and then they stroll off like you just offered them cardboard dust instead of a snack.

If you live with a picky or easily bored cat, you know the frustration: treats that smell great to you, but somehow don’t register on your cat’s internal snack radar. You want something that excites them every single time — not only as a reward, but as a little shared ritual between the two of you.

That's where Felix KnabberMix steps in.

Felix KnabberMix (often marketed as Felix Goody Bag or Felix Mix Snacks in English-speaking countries) is Purina's answer to the "my cat is totally unimpressed by treats" problem — a colorful, crunchy mix that many owners say their cats can identify just from the sound of the bag.

Why Felix KnabberMix Might Be the Treat You Were Missing

Felix KnabberMix is a mixed snack bag by Purina (under Nestlé S.A., ISIN: CH0038863350) designed to hit three things cats actually care about: smell, crunch, and variety. Instead of one boring shape and a single flavor, it combines different kibbles in one bag — typically poultry, fish, or cheese/meat-style mixes depending on the variant.

On Purina's official German site, Felix KnabberMix is described as a "supplementary feed" for adult cats: that means it's a treat, not a full meal, and should be given in moderation. But the way many owners talk about it online, you'd think it was cat crack (in the nicest possible way).

Why this specific model?

There are a lot of cat treats out there — soft sticks, jerky-style, freeze-dried meat, functional treats with hairball or dental claims. So why choose Felix KnabberMix over yet another bag of generic crunchy snacks?

• Multi-flavor mix in one bag – Instead of one monotone treat, KnabberMix usually combines three flavors in one pack (for example, poultry, liver, and turkey in some markets; or fish mixes in others). For your cat, that means each mouthful is a tiny flavor lottery.
• Crunchy texture that "feels" like prey – Cats are hardwired to enjoy that satisfying crunch. It mimics the sensation of biting into small bones or cartilage. Owners on forums repeatedly mention that their cats love the crunchy texture.
• Strong aroma that really gets their attention – Reddit and forum comments often say things like "my cat comes running as soon as they hear this bag" or "they can smell it from the next room." That powerful scent is a big part of the appeal.
• Easy to portion – Because the pieces are small, you can give just a few at a time and still feel like you’re really treating your cat without overfeeding.
• Widely available & budget-friendly – In European markets (especially Germany and the UK, where the similar Felix Goody Bag line is common), KnabberMix is easy to find in supermarkets and online, usually at a very affordable price compared to premium niche treats.

In real-world terms, this means Felix KnabberMix works exceptionally well as a training reward, bonding ritual, or recall tool. Need your cat to come inside at night? Shake the bag. Need them to associate the carrier with something positive? Drop a few KnabberMix pieces in there. The mix format and intense smell give you a lot of leverage.

What Users Are Saying

Across Reddit threads, Amazon-style reviews, and European pet forums discussing Felix treats (including Felix KnabberMix and its close cousin Felix Goody Bag), a clear pattern emerges: cats tend to go wild for these, even if their humans have a few reservations about the ingredient list.

Common positives:

• High palatability – Many owners report that this is the only treat their cat consistently accepts. Comments like "my cat is obsessed" or "they hear the bag and sprint" are frequent.
• Great training tool – Because cats value these so highly, they're often used for recall training, positive association with carriers, or rewarding nail trims and grooming.
• Fun ritual – Some owners build daily routines around a few KnabberMix pieces before bed or after work, turning it into a bonding habit both cat and human look forward to.

Common criticisms:

• Not the cleanest ingredient profile – Like many mass-market treats, Felix KnabberMix typically uses animal and vegetable by-products, cereals, and flavorings. On Reddit, more ingredient-conscious owners sometimes describe it as a "junk food" treat — something their cats love, but not a health food.
• Can encourage begging – Because cats become so fixated on the taste and smell, a few owners say they now have "treat monsters" who meow incessantly near the treat cupboard.
• Moderation required – Some reviewers emphasize sticking to the feeding guidelines on the pack. Overdoing treats (any treats) can add up in calories quickly.

Overall sentiment: if you see treats as an occasional joy and a way to strengthen your bond, Felix KnabberMix is widely loved. If you're extremely strict about only minimally processed, single-ingredient snacks, you'll likely see it as an "occasional fun junk food" to be rationed carefully — if at all.

Alternatives vs. Felix KnabberMix

The cat treat market is crowded, and it's useful to know where Felix KnabberMix sits on that spectrum.

• Felix KnabberMix vs. premium freeze-dried meat treats
  Freeze-dried chicken or salmon treats are typically made from a single ingredient, with no cereals or added flavorings. They're great if you want something very natural and high in protein. However, some cats actually prefer the intense flavors and crunch of KnabberMix, and freeze-dried treats are often significantly more expensive per gram.
• Felix KnabberMix vs. functional dental treats
  Dental treats from other brands may focus on plaque control or tartar reduction, with specific shapes or formulas. KnabberMix doesn't market itself as a dental product; its main goal is pleasure, not plaque management. If you want a single treat that also supports dental health, you may look to specialized options — but they may be less exciting to picky cats.
• Felix KnabberMix vs. soft stick treats
  Soft stick treats are easy to tear and great for older cats with dental issues. KnabberMix, by contrast, is all about the crunch. For young to middle-aged cats with healthy teeth, that crunch is a plus; for seniors or cats with dental problems, you might want to mix in some softer alternatives.
• Felix KnabberMix vs. other supermarket crunchy treats
  At a glance, KnabberMix doesn't look radically different from rival supermarket crunchy treats. What tends to set it apart, based on user discussion, is simply how irresistibly tasty many cats find it. It's often the "break glass in case of emergency" treat that works when nothing else does.

If you're trying to decide, ask yourself: is your top priority nutrition purity, or reliably high enthusiasm from your cat? Felix KnabberMix is firmly in the second camp.

Final Verdict

Felix KnabberMix is not pretending to be a nutraceutical miracle or a perfectly "clean label" snack. It's something far simpler, and for many cat owners, more important: a small, crunchy bag of guaranteed feline excitement.

When you strip away the marketing, what you get is:

• A highly tempting, crunchy treat mix most cats recognize and race toward.
• An affordable, easy-to-find reward that makes everyday life — from calling your cat inside to making the carrier less scary — dramatically easier.
• A shared ritual: that little rustle of the bag, the sound of fast paws on the floor, and the satisfaction of giving your cat something they clearly adore.

Yes, you should treat Felix KnabberMix like what it is: a pleasure snack. Follow the package guidelines, keep it occasional, and continue to base your cat's diet on a balanced, complete food. But used that way, it becomes less about nutrition and more about joy and connection.

If your cat seems unimpressed by their current treats — or you simply want a reliable "nuclear option" that cuts through feline indifference — Felix KnabberMix is absolutely worth having in your cupboard. Just don't be surprised if your cat learns the sound of the bag faster than any command you've ever tried to teach them.
