The science-backed, 100% plant-based premium gut-load for all your feeder insects. Roaches, crickets, mealworms & more. 9 superfoods. Zero compromise.
Every ingredient chosen for a reason. Every claim backed by peer-reviewed science.
Most competitors use a single vegetable — or none at all. We combine Carrots (16,706 IU) and Pumpkin (12,230 IU) for the highest Vitamin A content available in any gut-load formula.
Peer-reviewed research confirms Vitamin A deficiency causes dysecdysis (poor shedding) in reptiles.¹ Your gecko's healthy shed starts here.
Competitors use dog food loaded with CASEIN — a milk protein scientifically proven to cause 2× MORE uric acid buildup in insects than plant proteins.² Uric acid transfers to your gecko, causing gout and kidney damage.
We use only alfalfa, oats, and nutritional yeast. Pure plant nutrition. Zero risk.
4.2% Calcium with a high 14:1 Ca:P Ratio — that's 30–50% more calcium than leading brands. Metabolic Bone Disease (MBD) is the #1 killer of captive reptiles. We make sure your gecko never faces that risk.
Multiple independent studies confirm that excess dietary protein causes feeder insects to store uric acid in their fat bodies — uric acid that transfers directly to your gecko when the insect is eaten. Hamilton & Schal (1988, Annals of the Entomological Society of America) documented that high-protein diets cause toxic uric acid accumulation and early death in cockroaches. Cerreta et al. (2021, Zoo Biology) confirmed that surplus nitrogen from protein-rich diets is stored as uric acid in the fat body across multiple cockroach species. The Merck Veterinary Manual lists high-protein feeder diets as a known predisposing factor for gout in captive reptiles.
Critter Meal is formulated at exactly 15.0% protein — a conservative, research-supported threshold. Competitors often push 20–30%. Safe for roaches, crickets, mealworms, superworms, and more.
Beta-carotene (carrots & pumpkin), Lutein & Zeaxanthin (spirulina), and Anthocyanins (hibiscus) — four distinct carotenoids that research has experimentally proven to increase yellow and red coloration in reptiles.³
Bee Pollen — complete amino acids & minerals.
Spirulina — 60% protein, powerful antioxidants.
Hibiscus — Vitamin C & immune support.
Nutritional Yeast — full B-vitamin complex.
Competitors use wheat bran and corn meal. We use superfoods.
This is the most important thing you'll read about feeder insect nutrition. Most gut-load products on the market use dog food or cat food as a cheap protein source. Here's why that's a problem for every feeder insect you keep — and why we do things differently.
A landmark study by Mullins & Cochran (1975) found that casein protein — found in dog food and dairy products — causes 2× more uric acid accumulation in feeder insects compared to plant proteins at the same percentage. Uric acid doesn't stay in the insect. It transfers directly to your gecko when eaten, accumulating in joints and kidneys over time, leading to gout, organ damage, and shortened lifespan. This applies to all your feeders: roaches, crickets, and mealworms alike.
DL-Methionine is a synthetic amino acid added to virtually all commercial poultry feeds, pet foods, and many commercial gut-load products as a cheap protein booster. It is found in nearly every major cricket diet and feeder insect food on the market. Here is why it is a serious concern for reptile keepers.
1. It acidifies urine — and reptile kidneys cannot handle it. DL-Methionine is metabolized into sulfuric acid in the body, which lowers urinary pH. In mammals, this is sometimes used therapeutically to dissolve struvite bladder stones. But reptiles excrete waste as uric acid — not urea — through renal tubules that are highly sensitive to pH changes. Acidification of the renal tubular environment disrupts uric acid secretion, causing it to precipitate as crystals in the kidney tissue itself. This is a direct pathway to visceral gout and renal failure — the leading cause of death in captive insectivorous reptiles. Veterinary literature notes that DL-methionine has been experimentally used to deliberately damage renal tubules in reptile research models precisely because of this mechanism.
2. It is the D-isomer — not the natural form. Natural methionine in food is the L-isomer (L-methionine). DL-Methionine is a synthetic racemic mixture containing the D-isomer, which does not occur in nature. While the D-isomer can be partially converted to L-methionine in some species, this conversion is inefficient and places additional metabolic burden on the liver and kidneys. The excess D-methionine must be excreted — adding to the overall nitrogen load that the reptile's kidneys must process after eating gut-loaded insects.
3. It accumulates through the food chain. When feeder insects consume DL-Methionine-containing gut-loads, it is incorporated into their tissues. When your gecko eats those insects, it receives a concentrated dose of this synthetic compound — meal after meal, for the life of the animal. The long-term cumulative effect on reptile renal function is not well-studied, but the mechanism of harm is well-established in veterinary and comparative physiology literature.
Critter Meal contains zero DL-Methionine. Every gram of protein in this formula comes from whole food plant sources — alfalfa meal, rolled oats, spirulina, bee pollen, and nutritional yeast — that provide naturally balanced amino acid profiles without synthetic additives.
Critter Meal uses alfalfa meal, rolled oats, and nutritional yeast as its protein base. Together, these plant sources provide a complete amino acid profile — without casein, without DL-Methionine, and without the uric acid risk. Every feeder in your colony stays healthier, and so does your gecko.

Roaches & Crickets: Offer Critter Meal every other day, allowing the bowl to empty before refilling. Critter Meal can be served dry or mixed with a small amount of water to a soft oatmeal consistency — both work well. On off days, offer fresh greens (collard greens, carrots, squash). Always provide a moisture source such as fresh vegetables, fruits, or water crystals to keep your colony hydrated.
Mealworms: Critter Meal works great as a dry bedding substrate — simply pour it into the bin and let the mealworms burrow and feed freely. Alternatively, prepare a small wet mix in a shallow bowl or container. Always offer a separate moisture source such as carrot slices, apple pieces, or other fresh fruits and vegetables. Mealworms do not drink standing water and rely entirely on food for hydration.
Offer Critter Meal freely for 24–48 hours before feeding to your gecko. Then remove Critter Meal and offer fresh greens only for the final 12–24 hours before feeding off.
Dust feeders with calcium powder immediately before offering to your gecko and feed within 15 minutes of dusting for best results. If your gecko does not receive UVB lighting, use calcium + D3 at every feeding. If your gecko receives proper UVB, use plain calcium (no D3) — your gecko synthesizes its own D3 from the light and additional D3 supplementation risks overdose.
Just real, whole superfoods. Nothing else.
We don't make claims we can't support. Every key benefit is grounded in published research.
Hypovitaminosis A is a common nutritional disease in insectivorous reptiles. Dysecdysis (poor shedding) is the most common clinical sign and is directly linked to inadequate dietary Vitamin A.
Casein protein (found in dog food and dairy) caused double the uric acid accumulation in cockroaches compared to plant-based proteins at equivalent dietary percentages.
A controlled feeding trial using diets ranging from 5% to 65% protein found that high-protein diets caused toxic uric acid accumulation, distended abdomens, and early death in German cockroaches. Longevity decreased as dietary nitrogen increased.
A comparative nutrient analysis of four feeder cockroach species confirmed that surplus nitrogen from protein-rich diets is stored as uric acid within the fat body across all species tested, with elevated uric acid in females and adults.
A comprehensive review of renal pathology in reptiles documented that DL-methionine (seleno-DL-methionine) accumulates in prey animals and reaches significant concentrations in reptile tissues, with renal tubule damage being a documented outcome. The study confirmed that reptile renal tubules are experimentally vulnerable to chemical damage via dietary compounds that alter tubular function.
An experimental feeding trial demonstrated that dietary carotenoids are directly deposited in reptile skin tissue, with measurable increases in yellow and red chroma in animals fed carotenoid-rich diets.
Science-backed. Superfood-powered. 100% plant-based. Formulated at exactly 15% protein — a conservative, research-supported threshold backed by multiple peer-reviewed studies. One formula. Every feeder. Every gecko.
