Kittens are alittle roudy, like profitbob said. Mine use to hang upside down from all the drapes in the house by their claws and stare at me. LOL! I chose to have cats because they are sooo independent. When you are gone, if you leave enough food and fresh water, a couple scratch posts.. and a clean litter box, your cat, or cats can be fine without you for days.. infact I think they like having the place to themselves! So if you're a busy person who's not home much, I would suggest acouple cats. Mine are great companions, especially now that they're so far past that 'kitten' stage. They are alittle mischievous for the first few years, like all babies, you'll need to keep an eye on them, but they do settle down, a lot.
I could go on and on about the greatness of cats. I've had them in my life since I was a small child, they are my favorite domestic animal... so if there is ever anything more you'd like to know about them, don't hesitate to ask me. Good luck!
