Now he's a year and 6 months old.
I take him out about 2 - 3 times a week (offer it daily, but he doesn't want always) and my husband about once a week.
When Taco was younger than a year, I took him out once each 7 - 14 days, he just hadn't wanted more often.
(Not want = walks away and lies down a bit away. Like a cat not wanting to be picked up.)
When I take him out, he usually snuggles for up to 5 mins (5 mins rarely, rather 2 - 3), then runs around and climbs a lot until he starts to feel cold, and easily gets back into his enclosure. I've seen with gradually becoming an adult, he has become more confident and this is, I guess, why he wants to get out to explore more often. He's a calm, introvert guy, but not shy anymore. When he was younger, he was really shy and despite super curious, he was reluctant of new things - like: new things are for watching, and it's better if watching from a good distance.
I'm happy that he learned he can just jump off my hand when I put him back with a
little "hop" onto the next branch or platform, and doesn't need to fully jump down. These powerful jumps from the top of the enclosure (opens from the top) all the way down have scratched me often, but with just onto the next thing it's much softer - and it looks so elegant
