callie loves to jump and manages to get herself onto things i didn't think she could reach. of course i keep a close eye on her, but sometimes i turn my head for a minute and she's getting into trouble! she's still a hyper baby, unspayed though getting spayed in two weeks. she lives in a 4x4x4 dog pen, one level. i was thinking of getting her a two level cat tree, maybe one with a covered hut type thing on top, so that she'd be sort of contained. i'm not sure if it's a safe option, though i figure it's safer than finding her try to jump her way onto my dresser! she does have a ramp, custom built by a friend's husband, leading up to my bed so she can snuggle in the blankets and sit in the sun. that's the only "higher" space she has. if a cat tree is a bad idea, any other suggestions?

I like the idea of making something yourself (or having something made) because you have control over dimensions and materials.  

The easiest and cheapest thing you can do is get a clean cardboard box and cut a hole in it with a serrated knife (or a steak knife). If your bun chews it up it didn't cost you much (if anything) and is easy to replace. Your bun will appreciate the privacy and you will appreciate the cost.

If you want it to be 2-story it is easy enough to stack them, just make sure you secure them with hot glue or a good packaging tape in between (do not use duct tape as it does not adhere well to cardboard and it will not be sturdy). Just be sure any tape or glue is inbetween the two layers and does not wrap around the outside as it would be accessible to your bun for chewing.

i do have a cardboard box for her to hang out in/on. i was afraid to add a second level because i feared it wouldn't be sturdy enough.  granted, she only weighs three pounds!
