Cat Weight Kit is the purrfect cat weight management app, providing all the tools you need, whether your cat's goal is to maintain, lose, or gain weight. The 3 tools create a cycle to Assess → Track → Adjust, and repeat, for smart weight management — because it’s never a fixed, one-time plan. 1. Body Condition Score — ASSESS how much weight to lose or gain, or if weight is ideal • The best way to determine how under- or overweight a cat is, or if their weight is ideal, is with a hands-on and visual examination • Assessing your cat is simple with the comprehensive guide and quiz • Use your cat's score to estimate their ideal weight 2. Weight Tracker — TRACK if weight aligns with their goal to maintain, lose, or gain • Record weights, body condition scores, progress photos, and events that may impact weight • Visualize weight trends with the interactive chart • Set weight goals and colour-coded feedback shows if total and weekly weight changes are on track, along with the remaining weight to lose or gain 3. Food Calculator — ADJUST meal plan calories as needed based on weight trends • Create custom meal plans based on your cat's weight, activity level, and weight goal • Select the proportion of wet food, dry food, and treats, and choose the number of meals per day • Calorie calculations are estimates and can be fine-tuned to match your cat's specific requirements using the 'Adjust Calories' tool ________ Also recommended: • Digital baby/pet scales (kg or lb) • Digital food scales (grams) ________ Cat Weight Kit Is for Every Cat Overweight cats: • Body condition score your cat to determine how significantly overweight they are and estimate their ideal weight • Estimate your cat's daily calories and create custom meal plans with the exact amount of food (in grams) • Monitor weekly weight change and adjust meal plan calories as needed to aim for a weight loss of 0.5-2% of body weight per week — not too fast (which can lead to health complications) or too slow Underweight cats: • Body condition score your cat to determine how significantly underweight they are and estimate their ideal weight • Create custom meal plans with increased calories that support weight gain • Monitor weight changes in response to diet and treatment plans to make informed decisions that support health Ideal weight cats: • Regularly assess body condition and take action if your cat starts to lose their healthy shape • Estimate your cat's daily calories and create custom meal plans with the exact amount of food (in grams) • Monitor total weight change and adjust meal plan calories as needed to maintain a healthy weight — while weight gain usually indicates overfeeding, weight loss may indicate underfeeding or a health issue requiring veterinary attention. Substantial weight changes (>5% from baseline) are highlighted for immediate attention Stop guessing.
