Furry Fibonacci Numbers

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.
