Expert answers to common cat nutrition questions.
保持理想的身体状态是确保猫咪长寿健康最有效的方法之一。家猫肥胖是一个日益严重的问题。通过使用 PetlyInfo 计算器，您正在主动管理宠物的代谢健康。
静息能量需求 (RER) 代表猫在休息时消耗的能量。我们的算法使用指数公式 70 × (体重 kg)^0.75，这是现代兽医营养学中最准确的临床标准。
猫的需求不仅取决于体重。是否绝育、年龄阶段以及活动水平等因素都会影响最终建议。我们的工具会自动应用这些系数，提供定制的方案。
体重只是一个数字，而 BCS 提供了背景。我们建议进行“肋骨测试”：您应该能够通过轻触感觉到猫的肋骨，但不应明显突出或埋在厚厚的脂肪下。
避免“极端节食”至关重要。猫的代谢非常特殊，如果减重过快，容易导致肝衰竭。目标是每周逐渐减轻总体重的 1-2%。
"目标不仅仅是体重秤上更小的数字，而是一只更有活力、更快乐的猫。良好的营养是猫咪健康的基石。"

A balanced diet for a feline is vastly different from that of a human or even a dog. As obligate carnivores, felines have unique physiological requirements that must be met through their daily intake. This guide covers the critical macro and micro-nutrients your pet needs for a thriving life.
Protein is the most critical component of a feline's diet. It provides the essential amino acids required for maintaining muscle mass, supporting the immune system, and producing vital enzymes and hormones. Unlike humans, felines use protein as their primary source of energy.
Dietary fat is a concentrated source of energy, providing more than twice the calories of protein or carbohydrates per gram. It also enhances the palatability of food, making it more appealing to your pet. More importantly, fats are essential for the absorption of fat-soluble vitamins (A, D, E, and K).
While felines do not have a biological requirement for carbohydrates, they can still utilize them as a secondary energy source if they are properly cooked and highly digestible. In modern commercial diets, carbohydrates often serve as a fiber source to support digestive health.
Taurine is an amino acid that is found almost exclusively in animal tissues. Unlike most other mammals, felines cannot produce sufficient taurine within their own bodies. A deficiency in taurine can lead to severe health issues, including dilated cardiomyopathy.
Felines evolved from desert-dwelling ancestors and consequently have a low thirst drive. In the wild, they obtained most of their hydration from the moisture content of their prey. In a domestic setting, especially for those fed exclusively dry food, ensuring adequate water intake is vital.
Always consult your veterinarian before making significant changes to your pet's dietary regimen.
Fact: Most adult felines are actually lactose intolerant. Giving them cow's milk can lead to severe gastrointestinal distress, including cramps and diarrhea.
Fact: Raw diets carry a significant risk of pathogens like Salmonella and Listeria. If you choose a raw diet, it must be formulated by a professional.
Fact: Protein does not cause kidney disease in healthy pets. Healthy felines require high protein levels to maintain their lean body mass.
