Our pets want to eat our food, sleep on our beds, and play our games. Some guy trained his cat to play Jenga, where you pull wooden blocks from a stack without making it fall. The cat is pretty good at it, as you can see in this quick video. How tall can she go without crashing?

*Wee ones:* Those blocks are rectangles. Can you find 1 shape in your room that looks like that?

*Little kids:* If the guy takes the 1st turn, then the cat goes next, then the guy to repeat…who takes the 7th turn? *Bonus:* Who takes the 18th turn?

*Big kids:* If a 12-layer stack has 3 blocks in each layer, and they remove the center block from each layer and stack them in new 3-block layers on top, how many new layers do they add? *Bonus:* If then the top half of the blocks in this restacked tower (*not* half the layers!) come crashing down, how many layers are left standing? (Hint if needed: How many blocks does this tower have?)

Answers:*Wee ones:* See if you can find a 6-sided rectangle box, like a shoebox!

*Little kids:* The guy, since 7 is an odd number. *Bonus:* The cat, since 18 is an even number.

*Big kids:* There are 4 new layers, since 12 blocks get removed and restacked. *Bonus:* The bottom 9 layers. There are 36 blocks in total, so the bottom 18 blocks stay standing. They take up 9 layers since the whole bottom 12 layers have just 2 blocks per layer.
