A strange mixture of birthday party planning, birthday present searching and math magic landed the new #MathShack mascots in my house. Seems the “Furry Fibonaccis” are here to stay.

### They are Fibonacci numbers in action!

Notice there is one white bunny (already named Abek). And ** one** is a Fibonacci number.

There are two brown bunnies (yet to be officially named). And ** two** is a Fibonacci number.

And there are ** three** total bunnies, another Fibonacci number.

My friend Lisa Pennington assured me that a fluffy addition would not break the bank. Apparently, she didn’t realize that I would end up with **three** of these furry cuties.

### We’ll see…

It’s not so easy to determine the sex of these three little guys.

Assuming there’s an equal probability of a rabbit giving birth to a male as a female, I have a one in four chance that they won’t be able to reproduce.

### Keep your fingers crossed for me!

According to the traditional Fibonacci rabbits explanation, each pair of rabbits can reproduce every month.

Keep your fingers crossed that I get lucky, and we don’t end up with 987 bunnies a year from now!

### But they ARE cute!

K8 totally loves them. And they’re a great way to teach caring, responsibility and, well… maybe the facts of life.

And if we ** do** end up with 987 bunnies next year, we’ll have an economics lesson too. After all, I paid $10 for each of these – that could be a significant profit!

Have you ever had bunnies? What do you think’s going to happen with Kate’s Furry Fibonaccis? Share your thoughts in the comments, and on twitter.
