How We Ranked These
Every food on this list was scored using KibbleIQ’s ingredient analysis rubric, which evaluates protein quality, filler content, preservative safety, and ingredient transparency on a 0–100 scale. For Bengals with diabetes, we weighted Bennett 2016 (Journal of Feline Medicine and Surgery) on the low-carb glargine remission protocol, Rand 2009 (Veterinary Clinics of North America) on feline diabetes pathophysiology, Rand 2004 (Journal of Veterinary Internal Medicine) on feline carbohydrate metabolism, Lederer 2009 (JFMS) on breed-specific feline diabetes prevalence, Roomp 2009 (JFMS) on intensive-management diabetic remission, Larsen 2003 (JAVMA) on feline obesity prevalence, O’Neill 2016 (JVIM) on feline diabetes epidemiology, Verbrugghe 2014 on feline carbohydrate metabolism, the AAFP/ISFM 2018 diabetes consensus, AAFCO Cat Food Nutrient Profiles for obligate-carnivore taurine and arachidonic acid requirements, and Kanchuk 2003 on protein metabolism in cats.
Our ranking weights low carbohydrate (less than 10% metabolizable energy from carbohydrate per Bennett 2016), elevated animal protein (target greater than 40% DM for obligate-carnivore feeding), named-meat-first ingredient quality, and inclusion of high-bioavailability palatability features (raw inclusion, marine protein) that maintain food intake during diabetic management.
Our Top 5 Picks
1. Instinct Raw Boost — A (90/100)
Instinct Raw Boost earns the highest ingredient-rubric score on this list (A/90, post-Session 60.6 verification) thanks to chicken meal and chicken first ingredients, freeze-dried raw chicken inclusion, and minimal carbohydrate fraction (less than 10% ME-carb in the Original Real Chicken variant). The freeze-dried raw inclusion supports palatability for diabetic cats whose appetite may be reduced during hyperglycemic episodes or insulin transition periods.
For Bengals in active diabetic management with insulin glargine, Instinct Raw Boost provides the high-protein low-carb substrate consistent with the Bennett 2016 remission protocol. Read our full Instinct Raw Boost review → · Shop on Amazon →
2. Orijen Cat — A (90/100)
Orijen Cat delivers 90% animal ingredients via the WholePrey formulation - fresh and raw chicken, turkey, fish, and organ meats with minimal plant fraction. Per the Champion Petfoods nutrient profile, the carbohydrate fraction runs 17-19% ME, slightly higher than the Bennett 2016 less-than-10% target but substantially lower than typical commercial dry kibble (35-50% ME-carb). For Bengals where palatability and high biological-value protein matter operationally, Orijen Cat is the premium dry-format option.
For Bengal owners willing to feed at premium-tier price points, Orijen Cat offers among the highest biological-value protein and lowest carbohydrate fractions in commercial dry kibble. Read our full Orijen Cat review → · Shop on Amazon →
3. Acana Cat — A (90/100)
Acana Cat is the value-tier sibling of Orijen Cat from the same Champion Petfoods manufacturer, delivering 75% animal ingredients with similar named-meat-first ingredient profiles. The carbohydrate fraction runs slightly higher than Orijen but remains substantially lower than typical commercial dry kibble. For Bengals on chronic insulin management with diet-driven remission as the goal, Acana provides the high-protein low-carb substrate at a more sustainable chronic-feeding price point.
For Bengal owners seeking high ingredient-rubric quality at lower price than Orijen, Acana Cat is the practical mid-premium choice. Read our full Acana Cat review → · Shop on Amazon →
4. Tiki Cat — B (78/100)
Tiki Cat is a wet-food primary-diet brand featuring marine protein (tuna, mackerel, prawn, anchovy) with minimal carbohydrate fraction - typically less than 5% ME-carb across the line. Wet-food primary feeding is operationally meaningful for diabetic cats per the AAFP/ISFM 2018 diabetes consensus: the higher water content supports hydration during hyperglycemia-induced osmotic diuresis, the meal-based feeding pattern (vs free-feed dry kibble) aligns with insulin glargine timing, and the marine-protein-first matrix delivers the obligate-carnivore protein density Bengals need.
For Bengals where wet-food primary feeding is operationally feasible and the owner can transition the cat from dry kibble (a process that typically takes 2-4 weeks), Tiki Cat provides the lowest-carb high-protein substrate at a non-prescription price point.

5. Hill’s Prescription Diet m/d Glucose — (Veterinary Prescription)
Hill’s Prescription Diet m/d Glucose is the prescription veterinary diet purpose-built for feline diabetes management - low-carbohydrate (approximately 14% ME-carb), high-protein (greater than 50% DM), AAFCO feeding-trial substantiated, and WSAVA Pillar 2 compliant. The formulation includes built-in L-carnitine supporting fatty acid metabolism during the lipolytic state of insulin-deficient diabetes. Available in dry and wet formats; the wet format is the operationally preferred option per AAFP/ISFM 2018 for the hydration and meal-pattern reasons noted above.
For Bengals where the dermatology, gastrointestinal, or other concurrent disease workup recommends a feeding-trial-substantiated prescription diet alongside insulin therapy, Hill’s m/d Glucose is the WSAVA-aligned prescription option. Discuss with your veterinarian. Read our full Hill’s Prescription Diet Metabolic review → · Shop Hill’s prescription on Chewy (Rx required) →
What to Look for in Food for a Bengal with Diabetes
Less than 10% ME from carbohydrate per Bennett 2016. The 63-cat prospective study by Bennett 2016 demonstrated 84% diabetic remission in newly-diagnosed cats on a less-than-10% ME-carb diet plus insulin glargine. ME-carb is calculated from the guaranteed analysis (or manufacturer-published nutrient profile) using the modified Atwater formula. Most commercial dry kibbles run 30-50% ME-carb; most prescription diabetic diets and high-protein wet foods run less than 15% ME-carb.
Wet food primary feeding is operationally preferred. Per the AAFP/ISFM 2018 diabetes consensus, wet food primary feeding in diabetic cats supports hydration during hyperglycemia-induced osmotic diuresis, aligns meal-based feeding with insulin glargine timing, and typically runs lower in carbohydrate than equivalent dry kibble. Transition from dry to wet over 2-4 weeks - cats are habit-driven feeders and abrupt transitions often produce intake refusal. Tiki Cat, Hill’s m/d Wet, and Royal Canin Diabetic Wet are the operational options.
Insulin glargine is first-line per AAFP/ISFM 2018. The AAFP/ISFM 2018 diabetes consensus recommends insulin glargine (Lantus) as first-line insulin for newly-diagnosed feline diabetes. Glargine combined with a less-than-10% ME-carb diet produces the highest documented remission rates per Bennett 2016. Home blood glucose monitoring with a feline-validated meter (AlphaTRAK 2 or 3) is the operational reference; nadir blood glucose should target 80-150 mg/dL on the glargine plus low-carb protocol. Discuss the protocol and monitoring schedule with your veterinarian.
Body condition score 4-5 of 9 supports diabetic remission. Per the AAFP/ISFM 2018 consensus and Larsen 2003, obesity is the most actionable modifiable feline diabetes risk factor. Bowl-portion feed twice daily using a kitchen scale; do not free-feed; treats limited to less than 10% of daily caloric intake. Re-weigh the cat at 4-week intervals targeting 0.5-1% body weight loss per week (cats lose more slowly than dogs and are at risk of hepatic lipidosis with rapid weight loss).
Watch for hypoglycemia during insulin therapy. Per the AAFP/ISFM 2018 consensus, insulin overdose or insulin-glucose mismatch can produce symptomatic hypoglycemia (weakness, ataxia, seizures, coma). Owners of insulin-treated diabetic cats should keep oral glucose gel or corn syrup readily available; symptomatic hypoglycemia is a veterinary emergency. The intensive home glucose monitoring per Roomp 2009 is the operational mitigation - early detection of trending hypoglycemia allows insulin dose reduction before symptomatic crisis.
Annual fructosamine and 12-week reassessment per AAFP/ISFM 2018. Fructosamine reflects average blood glucose over the prior 1-3 weeks - the operational marker for chronic glycemic control. Target fructosamine less than 400 micromol/L on glargine plus low-carb diet. 12-week reassessment of body condition, fructosamine, and remission status drives insulin dose adjustment and the diet-vs-prescription-diet decision.
Bottom Line
Bengals show elevated diabetes mellitus prevalence per Lederer 2009. Per Bennett 2016 (JFMS), low-carbohydrate (less than 10% ME-carb) high-animal-protein diets plus insulin glargine produced 84% diabetic remission in newly-diagnosed cats within 4 months. Per the AAFP/ISFM 2018 diabetes consensus, the dual-modality protocol is first-line. Wet food primary feeding is operationally preferred for hydration, meal-pattern alignment, and typically lower carbohydrate fraction. Body condition score 4-5 of 9 supports remission. Home blood glucose monitoring with feline-validated meter is the operational reference. Our top pick is Instinct Raw Boost for high-protein freeze-dried raw inclusion. Orijen Cat and Acana Cat are premium WholePrey alternatives. Tiki Cat is the wet-food primary-diet option. Hill’s Prescription Diet m/d Glucose is the WSAVA-aligned prescription option (Rx required). See also our general feline diabetes guide, general Bengal feeding guide, Bengal sensitive stomachs guide, and overweight indoor cats guide. For newly-diagnosed feline diabetes, work with your veterinarian on the glargine + less-than-10%-ME-carb protocol within the first 4 weeks of diagnosis - early aggressive management drives the highest remission rates per Bennett 2016.
