All's been going well so far; eating well, looking well, behaving well, really about the last challenge to go will be switching him to rats which I'll try once he reaches the 200 gram mark (which he's really close to, currently at 175 and should breach it by the time his current mouse supply is done).

However I've started looking into new housing for the future. Would like to get a T8 from Animal Plastics (especially because dealing with the humidity imbalance is getting tiresome), but the question is how long should I wait until he's old enough to feel comfortable in larger digs? A year old or so I'm assuming? He's already at 5 months and with how long they take to ship I'm wondering if it'd be a good idea to order one relatively soon, and the T8 model is currently on sale to boot.
