Not too bad, had the kennel by the bed and he slept for a solid 5 hours before needing to go out. Slept for another 2 and he was done lol. He’s not a huge fan of it when first going in but calms down pretty quickWell, how was the first night? That was always the worst. Kennel next to the bed it was we always did. Move it further and further away until you get them to a spot you want.
