I have two Yorkies and 2 sugar gliders! All of them are cuddly :)
Probably the best thing about sugar gliders is that you must bond with them; they get used to your habits and your scent and recognize you as a parental figure. The worst would have to be that males have a strange smell or scent they like to spray to mark their territory and all gliders are nocturnal. Which means if they want attention at night when they're up playing they bark just like little puppy dogs. They sleep all day.
Don't like Schizus and Hamsters bite!
