Peanut will do that with many things. Usually something new we brought in or if we re-arrange things in the house. She is a bit of a scaredy cat so she has to make sure everything is safe before she'll feel comfortable with it. When she is in bed with us, she will always stretch one paw out and tentatively "feel" then set it down. If that one goes good, she'll step with the other foot. We call that her "feeler" paw.
