Frequently Asked Questions

How many calories does a cat need per day?
An average adult cat (4-5 kg) needs approximately 200-300 calories per day. The exact amount depends on weight, age, activity level, and whether the cat is neutered. Kittens need more calories per kg of body weight for growth, while senior cats often need fewer calories.
Do neutered cats need fewer calories?
Yes, neutered and spayed cats typically need about 20-25% fewer calories than intact cats. Neutering causes hormonal changes that reduce metabolic rate and can increase appetite, making weight management especially important for fixed cats.
How do I know if I'm feeding my cat too much?
Signs of overfeeding include weight gain, difficulty feeling ribs under a layer of fat, loss of waist definition when viewed from above, and a hanging belly. Regular weigh-ins and body condition assessments help catch overfeeding early. Consult your vet if your cat's weight increases more than 10% above ideal.
