I totally agree about the commitment. We have lots of different kinds of pets at our house, and the sugar gliders definitely require the most, focussed time. My daughter takes Milton out when she gets home from school, and he rides around on her back, under her outer shirt, for as long as she'll keep him there (sometimes up to 8 hours). He is very bonded to her, but he still tolerates me. We have a new little girl, Stella, to keep Milton company, but we've only had her for about 3 weeks and she hasn't bonded to us yet, so we haven't been able to get the two together. She does nip occasionally at this stage of the game. She's frightened. We understand that patience is the primary value for now. We hope eventually she'll be riding around on someone's back, as well.
So, along with holding Milton several hours a day, we let them out to play for at least 1/2 hour each per day (separately, at this point). We hope soon to be able to let them out together for an hour. This requires being up and alert at about 11:00 p.m. Sometimes we let them out in the morning for a little while, too, if there's time.
They eat mealworms and a variety of fruits, veggies and grains. Stella likes chicken from Famous Dave's with the sauce taken off. Their diet needs to be varied and to include fresh foods. There is an alternative to trimming their nails by hand. We are very happy with our Wodent Wheel with its specially designed sandpaper insert, which files their nails down while they run.
We love our suggies. They are fascinating and full of personality. And perhaps some of what we love is their dependence on us and what we need to do for them on a daily basis.
