Mine like to climb. Last night I didn't secure their pen properly and I woke up with Claude in my bed. He was on one of my pillows chilling! I suspect Gus had been up at some point, I pulled some white fur off my face. I wish I had pictures but it was 3am and I was groggy because I was up in over an hour for work. Safe to say, I've made sure the boys are secure tonight.
One of the cons of the boys living together again after a few weeks of separation, is that together they get up to so much mischief. I love it. I do. The worst part is that my Labrador was in my bed and she didn't even twitch!!! She just ignored the bunnies hoping around and likely jumping on her.
