I found a very mild mannered friend for Bobbles today. After meeting a few possible candidates over the last couple days, this little guy chose me. He climbed right into my hand, up my arm, and sat on my shoulder sniffing my face. He was sweet with the other rats and way more laid back. He is a baby(which I hadn't planned to do). Intros went better than I thought. I was so nervous, but I wiped them down, rearranged and cleaned the cage, intoduced them in a laundry basket, and now they're building a nest together in the cage.
