Yes I have 3 cats right now. The oldest one doesn't have any interest in them. We have had her around chinchillas, birds, and rabbits since she was a kitten so she is pretty good with other animals. the sugar glider cage is on a stand so the cats can't get to them as easily. One of the cats is like obsessive about them. More the smell I guess than them, she will rub on and roll on anything with their scent. When I clean the cage she goes crazy climbing in it and rubbing on it. I'm not sure what the youngest cat thinks of them, she hasn't shown much interest but I imagin if they were loose she would chase after them. I make sure all cats are locked in another room when they are loose just to be on the safe side.
I did introduce one of them to one of my cats once. Tang was a very laid back lazy cat and I had one of the gliders out. So I let Tang see him. Sugar gliders make a really loud noise called crabbing that sounds kind of like a pencil sharpener when they are scared. Well the suggie crabbed and Tang took off as fast as he could haha. It was pretty funny, poor tang never came near me when I had the sugar glider pouch out again.
