Four Sugar Gliders Breeders

I have four healthy Sugar Gliders. They let you pet them, but they do not like to be held. They are still sweet, and will come to me. They come to me for food when I make a certain sound. They will adapt, and come to you also. The mom and dad are two years old and their kids are male and female, and are one years old. I am asking $450.00 for all four plus large cage, pouch, food, rolling ball and toys. Thank you
