**Growth Pattern via Weight Calculating**
Let's run through an example using one of my not-cats that I have information for from a young age: Daisycloud

Here's her info as I recorded it while she was growing up:

Kitten stats: 42 stat total

STR 4 | AGI 8 | HTH 5 | FIN 4 | CLV 7 | PER 7 | LCK 7

Weight: 4.5 lbs.

Adolescent stats: 76 stat total

STR 7 | AGI 14 | HTH 9 | FIN 7 | CLV 12 | PER 12 | LCK 15

Weight: 7.65 lbs.

Keep in mind for now that these were from before we had Students, but those will be addressed later.

The quickest way to get a growth pattern is to plug in the weights. I'll be using this

handy dandy calculator to make things easy. We'll be looking at the

**Whole Number Check** tab, which does math that takes advantage of the whole "no decimals in adult weights" thing.

Here's what it should look like once you've entered the info we have in to the yellow boxes. The name spot is optional and just for linking screenshots to the cat they're for.

We're looking for a row that highlights entirely in green and that has all the same number. For Daisycloud, that's the

**B|A** row. That means that she has a B|A (Arch) growth pattern and will weigh 9 lbs. as an adult. That means we're lucky- no more info needed for determining the growth pattern! (more complex cases will be addressed at the end of this post)

Next let's look at what to do with our new-found knowledge.

**Determining Adult Stats**
Now, for what you probably care about- your not-cat's adult stats.

We'll switch over to the

**Single Age Calculator** tab for this one.

Plug in the growth pattern from before and pick an age you have stat data for (the closest one to adult age is usually the most precise). Here's what it should look like:

That

**Adult Stat Ranges** section is what we're looking for. That's your not-cat's adult stats. And we're done!

**Incorporating Multiple Ages**
Right now, you can compare the predicted adult ranges by plugging in different ages and seeing what numbers overlap in order to get a more accurate prediction. I hope to have the calculator do this for you in the future.

**Student Stat Gains**
Students make the calculations a bit more complicated, but not by as much as you might think!

When a Student gains a stat to their final adult value, their current stats will actually update to reflect what the new adult number will be.

This means:

- If the Student's number for that stat
**CHANGES** after an increase...

...then their adult stat will be the highest previous prediction PLUS one

*e.g. If a Student had a FIN stat of 12 before a finesse increase and that stat is now 13,*

...and the adult prediction before they increased was 16-18,

...that means their adult FIN stat will be 18 + 1 = 19

- If the Student's number for that stat
**STAYS THE SAME** after an increase...

...then their adult stat's predicted minimum increases by one

*e.g. If a Student had a FIN stat of 12 before a finesse increase and that stat is still 12,*

...and the adult prediction before they increased was 16-18,

...then the new predicted range is 17-18

**More Complex Cases**
The example I gave above gave us a single potential answer using just two weights. That isn't always the case.

**Complications can include:**
- Multiple potential adult weights

*Sometimes the calculator will show you two fully viable adult weights. That means the kitten could have either as an adult, and as a consequence, any growth pattern associated with those rows.*

This is fairly common for cats with only a single weight value recorded. You will need more weight values to fully determine the growth pattern.

- Bugged young cat weights

*Prior to July 2022, there was a bug that caused young not-cats to display the wrong weights. If your data is very old, then it's possible you can't use that weight data.*

In this case, try plugging in stat totals into the **Stat Total Calculator** tab and looking to the colorful column to the right for the smallest numbers. Those will be the most likely growth patterns.

**Additional Tips and Tricks**
- An adult cat's weight can be a minimum of 4 lbs. and a maximum of 24 lbs.

*If any numbers are highlighted that are higher or lower than this, then you can rule out those associated growth patterns- they're not possible.*

- For cats that have biological parents

*A kitten's final adult weight will be any number between and including the adult weights of their biological parents. This can be used to rule out some potential weights shown on the calculator, and thus their associated potential growth patterns.*

- For cats that have biological parents with known growth patterns

*Knowing the growth pattern of even just one of the parents will help you narrow it down even further, letting you eliminate impossible inheritance patterns.*

North parents will give either of their genes to the first slot, South to the second, Trade to either. (A full guide on genetic patterns can be found here and a full guide on breeding and inheritance here)

**Conclusion**
Weight values are a much more accurate means of determining growth patterns, if that data is available to you. You can still do these calculations with just stat values, but there will be a larger potential margin of error, as these numbers aren't precise. Use all the records you have available to you and you'll have a perfect prediction in your hands.

Just make sure to have your calculator handy!
