Cat calorie calculator
Don't let your feline friend get "chonky." Calculate their exact daily needs based on their current weight and lifestyle.
Resting Energy Requirement (RER): 180 kcal
Most cat food labels are wrong
I genuinely believe that pet food companies want you to overfeed your cat. If you follow the label on the back of the bag, you’re often giving them 30% more calories than they actually burn, especially if they’re a "lazy indoor" house cat. Obesity is the #1 health problem in cats today, and it’s almost always because we trust the label more than the cat's actual weight.
This calculator uses the standard RER (Resting Energy Requirement) formula: RER = 70 × (body weight in kg)0.75. We then apply a multiplier based on whether your cat is fixed, active, or a growing kitten. Use this as a starting point, but always weigh your cat once a month to see if you need to adjust.
