Cat Weight Gain Calculator: A Simple Way to Track Your Kitten’s Growth

Ever wondered if your kitten is growing at a healthy pace? I did too when I adopted my fluffy little tornado, Luna. One day she looked tiny, and the next, she was knocking cups off counters like a pro. That’s when I realized—I needed a better way to keep track of her weight gain.

So I built a Cat Weight Gain Calculator. And guess what? You can use it too—right here in this post.

Why Track Your Cat’s Weight?

Let’s keep it real: cats don’t always look like they’ve gained weight. A healthy kitten should gain weight steadily, but not too fast or too slow. Here’s why weight tracking matters:

  • Helps you spot health problems early
  • Tracks kitten growth stages
  • Makes vet visits smoother
  • Keeps your cat at a healthy weight

Think of it like watching a child grow. You want to cheer them on, but you also want to make sure they’re on the right path.

How Does the Calculator Work?

It’s super simple math:

Growth Rate (%) = ((Current Weight – Previous Weight) / Previous Weight) Ă— 100

This gives you the total percent change. Then we break it down by day.

Let’s say:

  • Your kitten was 1.2 kg last month
  • Now she’s 1.5 kg
  • That’s a 25% increase over one month!

Boom. You’re now tracking like a pro.

Real-Life Example

When I started tracking Luna’s weight, I noticed something odd. One week, she gained 10% in just five days. That’s fast. I called the vet. Turns out, she was just going through a growth spurt. No big deal—but I felt good knowing for sure.

The calculator helped me stop guessing. And I loved watching her progress.

Normal Kitten Growth Rate (Quick Table)

Here’s a handy table so you know what to expect:

Kitten AgeAverage Weight Gain
0–2 weeks~10–15g per day
2–4 weeks~100g per week
1–3 months~250g per week
3–6 months~500g per month
6–12 monthsSlower growth

Note: Every cat is different! This is just a guide.

Tips to Help Your Cat Gain Healthy Weight

If your cat is underweight or growing too slowly:

  • Try kitten-specific food (higher calories)
  • Feed smaller meals more often
  • Check for parasites or digestive issues
  • Talk to your vet (always!)

Just like humans, cats thrive with love, care, and the right fuel.

Final Thoughts

Tracking your cat’s weight doesn’t have to be hard—or boring. With this simple Cat Weight Gain Calculator, you can keep tabs on your fur baby and feel confident in their health journey.

I made this tool for myself, but I hope it helps you too. Whether your cat is a sleepy sun-chaser or a wild sock thief, they deserve the best care.

Now go ahead—plug in your numbers and watch those gains!
