If you’ve been feeding your cat a raw or freeze-dried diet and feeling pretty good about it, the Go Raw recall saga of 2026 is worth sitting with for a few minutes. Not because raw feeding is inherently dangerous, but because this particular situation revealed something most pet owners, and honestly quite a few vets, don’t think about enough: a single missing B vitamin can quietly wreck a cat’s nervous system before you notice anything is wrong.

Here’s what happened. Go Raw LLC first recalled Quest Cat Food Chicken Recipe Freeze Dried Nuggets on February 17, 2026, citing low thiamine levels. Then they expanded the recall on February 26. Then again on June 8, 2026, this time pulling in Steve’s Real Food Freeze-Dried Chicken Recipe (lot C26022, best-by January 22, 2028) and additional frozen Quest lots. The FDA tested eight Quest Cat Food lots and found “extremely low or no thiamine” in all of them. In a March 13, 2026 advisory, the agency noted it had recommended Go Raw recall all eight lots, but as of that date the firm had only recalled three. These products reached consumers in at least 21 states, including California, Texas, New York, Florida, and Illinois.

What surprised me, going through all of this, is how long this took to fully surface and how many lots were involved before the picture became clear.

Why Cats Are Particularly Vulnerable to Thiamine Gaps

Thiamine, also called vitamin B1, is water-soluble and heat-sensitive. Cats can’t synthesize it on their own. Neither can dogs, but cats need roughly two to four times more dietary thiamine per day than dogs do, based on National Research Council guidelines. That gap matters enormously when a formula is deficient. A dog eating the same deficient food might stay asymptomatic longer, or never show signs at all. Your cat may not be so lucky.

The peer-reviewed literature backs this up. A 2018 review published in the Journal of Animal Science (available via PMC) laid out clearly how thiamine functions in cellular energy metabolism and why deficiency hits neurological tissue so fast. Brain and nerve cells are metabolically expensive. When thiamine drops, those cells feel it first.

This is the part I want owners to know cold, because the signs can look like other things, and time genuinely matters here.

Early signs tend to be subtle: reduced appetite, some lethargy, maybe a slight wobble you chalk up to a clumsy moment. Then things escalate. Advanced thiamine deficiency in cats causes a very specific neurological picture.

Clinical SignWhat You Might See at Home
VentroflexionCat’s neck droops downward, chin toward chest
AtaxiaWobbly, uncoordinated walking
CirclingCat walks in circles, often to one side
SeizuresConvulsions, muscle tremors, loss of consciousness
Dilated pupilsUnequal or abnormally large pupils

Here’s the genuinely good news: when thiamine deficiency is caught early and treated with B1 supplementation (typically by a vet, via injection at first), it’s generally reversible. Full stop. Cats can recover. The tragedy is in the cases that go too long without identification, because late-stage neurological damage can be permanent, and untreated deficiency is fatal.

If your cat is showing any combination of neck drooping, stumbling, or circling: this is an emergency. Don’t wait until Monday. Go now.

The Specific Products to Check Right Now

The June 8, 2026 FDA recall expansion is the most recent action, and if you have any Quest Cat Food products or Steve’s Real Food Freeze-Dried Chicken Recipe (lot C26022) in your home, stop feeding them immediately. Go Raw also enacted a full stop-sale of all Quest products across all retailers until thiamine content issues are resolved, so if you see Quest on a shelf somewhere, it shouldn’t be there.

Check your lot numbers against the FDA recall pages (linked in the sources below). I’ll be honest, this is genuinely the one step that’s worth five minutes of your time today if you feed any of these brands. The FDA’s recall database is searchable and clear.

The Bigger Question: Can You Trust “Complete and Balanced”?

The Go Raw situation has sparked a real debate in raw-feeding communities, and it’s a fair one. AAFCO’s “complete and balanced” labeling standard is supposed to guarantee nutrient adequacy, including thiamine. So how did multiple lots get through with zero detectable B1?

The research here is mixed, but the most likely culprits in freeze-dried and raw formats are manufacturing inconsistency and the heat-sensitivity of thiamine itself. Even low-temperature processing can degrade B1 if controls aren’t tight. A formula can be designed to meet thiamine requirements and still fail in a specific production run if something goes wrong upstream.

This doesn’t mean every raw or freeze-dried food is deficient. It means that “complete and balanced” is a label claim, not a real-time test result. Third-party batch testing exists, and some manufacturers do it. Asking your brand whether they test finished product for thiamine, not just formulate to meet it, is a reasonable question. A brand that’s confident in their QC should be able to answer it.

What to Do If Your Cat Ate Recalled Food

First, don’t panic, but don’t ignore it either. If your cat ate any recalled product and is showing neurological signs, get to a vet or emergency clinic today. Mention the thiamine recall specifically, so your vet knows what they’re working with.

If your cat ate recalled food but seems completely normal, call your vet’s office and describe the situation. They may recommend a check-in visit or monitoring at home depending on how much of the food was consumed and over what period. Document when you bought the product, the lot number, and how long your cat ate it. That history helps your vet make a good call.

The FDA also accepts MedWatch reports for pet food adverse events, and reporting matters. It’s how the agency builds the case to push companies toward complete recalls rather than piecemeal ones, which, based on the March 13 advisory, was exactly the pressure needed here.

Raw feeding isn’t going away, and for many cats it works beautifully. But this recall is a reminder that “natural” and “safe” aren’t synonyms, and that even well-intentioned formulas can fail in ways that are hard to see coming. Knowing the signs of thiamine deficiency, knowing which lots were pulled, and knowing when to call your vet instead of waiting: that’s the practical takeaway from a messy, still-unfolding situation.
