We had a cat named Nosey. And he realllly earned that name. He passed a few years back due to urine crystals and we had him put to sleep.
Nosey would get into everything. Once after putting Xmas decorations away in the attic, we all decided to go for a walk out in the snow. When we came back we couldn't find Nosey. So I said let's look in the attic. Sure enough once the hatch was opened up his little face poked out as if to say, "Hey, what's new? I meant to come up here."
The little bugger had climbed up the ladder and got stuck in the attic. But it was only for about an hour.
