Marley is very cute. Love the yellow eye turrets. Yes, the weather here in the Pacific NW is similar to yours. I noticed you have brick which is a great heat keeper. I also put my chams on my concrete patio next to the brick house which boosts the temperature up quite a bit.
I also love the little "no smoking" window/door sticker you have in the background. Haven't seen those over here. Marley will get used to the outdoors eventually. It is pretty overwhelming to see such a huge new world. Just don't leave his side for a second. Crows (assuming you have them) strike in moments. Several people on the forum have had their chams taken off.
On a better note....you have a healthy cute boy!
