Cat Weight Calculator and Tracker

Welcome to the Advanced Cat Weight Calculator! This tool is designed to help you track and manage your cat’s weight effectively. Whether you’re looking to maintain a healthy weight, monitor weight changes over time, or get personalized insights based on your cat’s breed, activity level, and age, this calculator provides all the tools you need.

How’s the Weight, Doc?

Many pet parents, whether they have cats or dogs, often ask this question during vet visits. However, it’s a topic that could benefit from more frequent discussions.

According to the Association for Pet Obesity Prevention (APOP)’s 2018 survey, about 70% of pet parents expressed a desire to discuss weight loss and diet with their vets, yet only 60% reported having these conversations. This indicates a gap in communication, often due to vets fearing they might offend pet parents or pet owners assuming their pet’s weight is fine if it isn’t mentioned.

A tool like a cat weight calculator can help bridge this gap by providing a starting point for these discussions. Instead of a vague, “How’s the weight, doc?” pet parents can ask, “The calculator suggests my cat is 2lb overweight. What can we do about that?”

How to Calculate Your Cat’s Ideal Weight

Most cats have an ideal weight range of 8-12 pounds, though this varies by breed. For example, Maine Coons are naturally larger and can weigh up to 25 pounds. To get more precise, assess your cat’s Body Condition Score (BCS), which measures fat percentage and determines a healthy weight.

For a BCS scale of 1-5, the scores roughly translate to:

• BCS 1: 30% underweight
• BCS 2: 15% underweight
• BCS 3: Ideal weight
• BCS 4: 15% overweight
• BCS 5: 30% overweight

You can calculate your cat’s ideal weight using this formula:
Ideal Weight = Current Weight × (100% – % Overweight)

Example:
For a 15lb cat with a BCS of 5 (30% overweight):

• Ideal Weight = 15lb × (100% – 30%)
• Ideal Weight = 15lb × 0.7 = 10.5lb

What’s Too Heavy for a Cat?

An ideal body fat percentage for cats is around 20%, corresponding to a BCS of 3. Cats at this score have a light fat covering, ribs and hips that can be felt but not easily seen, and a visible waistline.

While most cats fall between 8-12 pounds, size matters. For instance:

• Cats longer than the average 18 inches (excluding tail) may weigh more.
• Smaller cats may need to stay under 10 pounds.

How Much Should I Feed My Cat to Lose Weight?

To help your cat lose weight, start by determining their ideal weight. Use a cat weight calculator to estimate daily calorie needs based on food kilocalories (kcal).

For a 10lb cat with an ideal weight, aim for 180-200 calories per day. For weight loss, feed about 80% of that:

• Example: 200 kcal × 0.8 = 160 kcal/day

To calculate portions:

• If food contains 350 kcal per cup, divide 160 kcal by 350.
• 160 ÷ 350 = ~0.46 cups/day.

Do Cats Lose Weight as They Age?

Age alone doesn’t cause significant weight loss, but older cats (15+ years) may experience mild muscle loss, noticeable along the spine. However, noticeable weight loss is usually due to underlying conditions like kidney disease, diabetes, or cancer.

Conversely, some cats gain weight with age as their activity levels decline, reducing energy needs. Each cat is unique, so any weight changes should be discussed with your vet.
