Thanks for all the kind replies everyone! I didn't spend the night last night (wanted to spend time with my kitties) But Alexa said he did great! He spent the night in his kennel like a good boy, then in the morning when she took him out he went potty right away. She said she let him see the kitties through the baby gate and he paid no attention to the cats. I'll be there tonight so I'll try to take some more pics!
