Definitely. Ours decided to rip a hole in the dust cover underneath the box springs to our bed and crawl in there. We ended up laying paneling down on the bed frame to keep them out of there.
Another time, I was painting the spare bedroom and had removed the vent covering the cold air return. I opened the door for a minute to do something, noticed the male cat nearby, but didn't pay much attention. Going back in the room a few minutes later, and no cat. Yes, he had gone through the cold air return. Luckily, as I was contemplating how to get him out of there, he crawled out.
