I've found out we're having a boy but I still want to go with a neutral animal theme. Just a couple of questions for those of you who have already done their decorating.

We're not allowed to paint (we rent) but I was planning on getting some wall decals, and maybe one of those ceiling nets full of stuffed animals. Any other suggestions on how to decorate a room that has to stay plain white walls?
I really love the elephants, tigers, 'jungle' animals, but I also really love owls, deer, 'forest animals', do you think mix and matching these would look silly or would it still be cute?
Lastly, where are you guys getting your stuff?

I've been checking amazon and etsy but the cutest things always seem to be just out of my price range.
