Ready Cal High Calorie Powder Supplement for Cats
Verified Jun 20, 2026
This is a high-calorie powder supplement designed to help cats who need extra energy or support gaining or maintaining weight. It uses chicken meal and coconut powder as main calorie sources and is fortified with a range of vitamins and minerals. The powder can be sprinkled over regular food or mixed with warm water into a gravy, making it easier to encourage eating in kittens, adults, and senior cats.
This is a thoughtfully formulated high-calorie supplement for cats who need extra energy on top of their regular balanced diet, such as those who are underweight, recovering, or fussy eaters. The product provides concentrated fat-based calories with added vitamins and minerals and a straightforward ingredient list. It’s best used as a topper or short-term support alongside a complete cat food, rather than as the main diet.

KibbleLab Review
Strengths
- High fat content (22% min) and approximately 20 kcal per scoop provides a dense source of extra calories in a small volume, helpful for cats with low appetite.
- Contains named animal protein (chicken meal) plus coconut powder and molasses for palatability and energy, which can make food more appealing.
- Fortified with multiple vitamins and minerals, including vitamins A, D3, E, and B-complex, to support overall nutrient intake during periods of increased need.
- Simple, dry powder format that can be sprinkled on food or made into a gravy, offering flexibility for picky or unwell cats.
Considerations
- This is a supplement, not a complete and balanced diet, so it should only be used alongside a regular, nutritionally complete cat food.
- Chicken meal is the primary protein source, so it is not suitable for cats with chicken allergies or known sensitivities to chicken.
- The combination of fat, coconut powder, and molasses makes this quite energy-dense; overuse could contribute to excessive weight gain if portions aren’t monitored.
- Contains added salt, which is fine for most healthy cats but may not be ideal without veterinary guidance in cats with certain heart or kidney conditions.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
02
Coconut
Coconut is used in pet foods primarily as a source of fat (often via coconut oil) and fiber, supplying medium-chain triglycerides (MCTs) such as lauric acid that can provide quick energy and may support skin and coat health in dogs and, to a lesser extent, cats. While small amounts can offer benefits like improved coat condition and possible antimicrobial effects, coconut is calorie-dense and can cause gastrointestinal upset, weight gain, or contribute to pancreatitis in susceptible pets, so it should be used sparingly and not as a substitute for balanced protein sources; avoid sweetened or xylitol-containing coconut products.
03
Cane Molasses
Cane molasses is a viscous sweetener and palatability enhancer used in pet foods and treats to add simple carbohydrates, help bind ingredients, and contribute trace minerals like iron, calcium, potassium and magnesium along with small amounts of B vitamins. It can improve taste and texture but is high in sugars and calories, so it should be used sparingly—excessive intake can contribute to weight gain, dental issues, or unstable blood glucose in diabetic or obese pets.
04
Maltodextrin
Maltodextrin is a processed, rapidly digestible carbohydrate commonly used in pet foods and treats as a binder, bulking agent, texture improver and flavor carrier. It supplies easily metabolized calories but offers little in the way of vitamins, minerals or fiber, so excessive inclusion can contribute to weight gain or blood sugar spikes in obese or diabetic dogs and cats, and it may cause digestive upset in sensitive pets; sources can include corn, wheat, potato or rice, so check for potential allergen concerns.
05
Dicalcium Phosphate
Dicalcium phosphate is an inorganic mineral supplement commonly added to dog and cat foods to supply concentrated, bioavailable calcium and phosphorus for healthy bone and teeth formation as well as general metabolic processes. It must be used in balanced amounts (typical Ca:P targets ≈1:1–1.4:1) because improper ratios or excess phosphorus can contribute to skeletal problems in growing animals and worsen conditions like chronic kidney disease, so formulation and dosing should be carefully controlled.
