A mind always wanting to do new things for fun or learning. Opening the door is something they enjoy doing for fun or learning all of them take having fun or going new places very seriously so allowing them to have a safe place in the house does them a lot of good health-wise for exercise or general exercise they need to do to keep healthy No limit to what they can do more less so always be aware they can fit under most things or slide through things very fast and efficiently overall. Play them doing what they can do is a lot of fun plus makes them happy since they are very much social characters for most of the time which is a great experience short term or long term the whole playtime with them as such do it everyday of the week ferrets need you as much as you need them. https://www.funwithferrets.co.uk/2024/11/rat-tail-how-to-cure-it.html
All fuzzbubbys know time well so if you get up normally at 8am they will expect you to do that always such as if you put them out to play at 9am they will expect you to do that all the time more less. I am not sure how they workout the time but they can do it well either way at 1pm they are always ready to get a walk since always do it around that time so if you do nothing at that time may get them annoyed some of the time so be aware of doing things since if the time is wrong it may annoy them sometimes so try and keep as much as possible to good timekeeping record with the fuzzbuddys https://www.funwithferrets.co.uk/2024/10/how-to-relax-angry-ferret.html
