I feel your pain. Every day, I'm putting something else away, and my twins are 10 months old now!
That's not said to scare you by any means. I love my girls. But I got very lucky with Cinderella -- and especially Cleo. She was a little over one when she adopted me and never did a naughty thing - until the twins got here.
Seriously, put away anything you don't want damaged. They don't mean any harm, they're just curious. I recently had to take my favorite painting off the wall because they could jump up off the back of the sofa and reach it. I didn't want to take a chance of them tearing it.
If you can afford it, now would be the best time to add another kitten. My twins will spend hours chasing each other and playing. If not, patience and game-playing will be necessary. Cali was my biter and it took almost two months of pushing her away when she bit me for her to get the message. Now, she'll put her teeth on my hand, look at me (as if to say "psyche!") and then lick me.
I'd love to see pictures. We have an awful lot of Siamese cat lovers here, including myself.
Good luck with whatever you decide.
