What’s in it
The entire ingredient panel: Water, Tuna, Tapioca, Natural Flavors, Guar Gum, Natural Tuna Flavors, Fructooligosaccharide, Vitamin E Supplement, Green Tea Extract. Nine ingredients. Each 0.5-oz tube delivers approximately 6 kcal. The product carries the AAFCO “intermittent or supplemental feeding only” statement.
Guaranteed analysis: 7% crude protein minimum, 0.2% crude fat minimum, 0.3% crude fiber maximum, 91% moisture maximum, vitamin E minimum 310 IU/kg, taurine minimum 0.025%. The 91% moisture is the defining feature — this is essentially a protein-flavored hydration delivery system rather than a traditional crunchy or semi-moist treat.
Inaba is a Japanese company (established 1805) that pioneered the lickable cat-treat format. The Churu line is their flagship product and has defined the lickable-puree category worldwide.
The good stuff
Simple, clean panel. Named fish protein (tuna) as the primary active ingredient after water. Our rubric awards +12 for a named whole-muscle fish protein in a multi-ingredient treat, and the function-class bonus for lickable-puree is +2. For cats specifically, the wet-format protein-first bonus stacks +3 cumulative when function class is lickable-puree AND first active ingredient is named protein AND no grain/starch in top 5 — Churu qualifies for all three.

91% moisture content is genuinely functional, not marketing filler. Cats evolved as desert-adapted carnivores and have a weak thirst drive relative to their water needs. Cats on dry-kibble-only diets are chronically mildly dehydrated — this is a documented contributor to feline chronic kidney disease (CKD) over time. Adding moisture-rich treats like Churu to a dry-kibble feeding pattern meaningfully increases daily water intake. For cats with early-stage CKD, diabetes, or urinary tract issues, the hydration contribution from a daily Churu tube is clinically meaningful.
Fructooligosaccharide (FOS) at position seven is a prebiotic fiber that supports beneficial gut bacteria. Research in cats shows FOS supplementation supports microbiome diversity, which is associated with better immune function and GI regularity. Our rubric doesn’t have a specific FOS line, but the preservation of a prebiotic in a clean panel is a positive signal.
No grains, no starches (except tapioca as thickener), no artificial colors, no artificial flavors, no synthetic preservatives, no carrageenan (−6 deduction that many wet cat foods incur). Natural vitamin E preservation and green tea extract as stabilizer.
Tapioca and guar gum as thickeners — both are food-safe and in minor quantities. The rubric considers guar gum neutral (not a rubric deduction unless combined with xanthan gum in excess). Tapioca is a refined starch that the rubric gently deducts for in biscuit/kibble context, but in the lickable-puree category it’s a reasonable texture-control ingredient.
There are no active FDA recalls or enforcement actions on Inaba Churu product line as of this review’s verification date.
The not-so-good stuff
Water as the first ingredient (by weight). Our rubric normalizes for this in the Fresh rubric by stripping water/broth and re-ranking, but the Treats rubric doesn’t have an explicit normalization step. The analyzer correctly recognizes water-first as category-normal for lickable-puree and doesn’t heavily penalize; however, if you’re comparing Churu to a dry single-protein treat like PureBites (A/95), the water-forward profile means less absolute nutrition per gram.
Tapioca at position three is a refined starch acting as a texture thickener. In a lickable-puree, this is a functional necessity — without a starch binder, the product separates. Our rubric doesn’t heavily penalize tapioca in the treat category, but it’s the main reason Churu scores 90 rather than 95 like PureBites.
“Natural Flavors” at position four is less transparent than whole-food flavoring. Natural flavors can include broad categories — Inaba doesn’t specify whether this is tuna-derived, chicken-derived, or something else. The “Natural Tuna Flavors” at position six suggests at least some of the flavoring is species-appropriate, but the ambiguity is worth flagging.
Mercury concerns are worth noting for any tuna-based cat product. Tuna accumulates trace mercury through the marine food chain, and chronic high-volume tuna feeding in cats can contribute to mercury accumulation over time. Inaba discloses their tuna sourcing on packaging but doesn’t publicly report mercury testing results. For cats fed Churu 1–2 tubes daily, mercury risk is minimal; for cats fed Churu as a meal substitute or in very high volume, consider rotating with chicken or salmon Churu variants to reduce cumulative tuna exposure.
High salt content is common in wet-format cat treats for palatability; Churu’s specific sodium content isn’t loudly disclosed but the format is salt-moderate by category. For cats on sodium-restricted diets (advanced CKD, heart disease), check with your vet.
How it compares
Churu A/90 and Tiki Cat Stix Tuna (A/90) are tied at the top of the lickable-puree category for cats. Tiki Cat Stix leads with tuna, chicken broth, then chicken; Churu leads with water, tuna, then tapioca. Tiki Cat Stix has slightly more named-protein content upfront; Churu has a simpler tail with fewer synthetic-style additives. Both are excellent; the choice is cat-preference driven. Many households use both for variety.
Against PureBites Freeze-Dried Chicken for Cats (A/95), Churu loses 5 points primarily to the multi-ingredient panel (water + tapioca + thickener vs. PureBites’s single-ingredient chicken). For nutritional density per gram, PureBites wins; for hydration-contribution and for cats that don’t tolerate crunchy textures, Churu wins. The choice depends on which dimension matters for your cat.
Against Greenies Feline Original (C/61), Churu is a 29-point improvement on ingredient cleanliness. Different jobs though: Greenies is a VOHC-accepted dental chew; Churu is a hydration-and-enrichment treat. Don’t substitute.
Against mainstream cat biscuits — Temptations (D/38), Friskies Party Mix (D/42) — Churu is a 48+ point improvement. The mainstream biscuits stack BHA + BHT + artificial colors + by-product meals that Churu avoids entirely. If your cat accepts the lickable-puree format, switching from a mainstream biscuit to Churu is a major quality improvement.
The bottom line
Inaba Churu Tuna Recipe earns an A grade (90/100) on KibbleIQ’s treats rubric — a top-tier lickable-puree cat treat with a clean panel and a genuinely useful 91% moisture content. At 6 kcal per tube, 1–2 tubes per day fits inside any cat’s 10% treat budget with room to spare, and the hydration contribution is clinically meaningful for cats on dry-kibble primary diets. Rotate with chicken or salmon variants if you’re feeding daily to reduce cumulative tuna exposure. For the absolute cleanest cat treat panel, PureBites (A/95) is the top pick; for the lickable format specifically, Churu ties with Tiki Cat Stix.
