My cats do but I'm starting to rethink the idea. They keep waking us up at 5am or earlier with their playing (they like to start wrestling each other in the bed or clawing/biting at our hair) and I don't have to get up for another 45 minutes at that point. It's incredibly frustrating. I also leave for work at 7 so I do have to feed them in the morning, which is why I think they've gotten into the habit. Any tips? Should I shut them out of the bedroom? I love letting them sleep with me... but they're making me lose sleep.
