Thank you sooooo much for coming on here! I know this is going to be hard to hear, but anything PPP told you-disregard. That includes the heat rock, diet, and living alone. We would be happy to tell you about there lies in due time if you want to know, but in the meantime: Keep your kitties away from your baby!
Your cats can and probably will attack and eat your glider. It doesn't matter that they aren't a rodent and don't smell like one. Rabbits, birds, and lizards aren't rodents, yet my cats seem to think they are fitting presents for my doorstep. Sugar gliders should not be allowed near dogs, cats, or birds. It is dangerous for them, and it is far better to keep them not only separate, but not in the same room. A cat can easily claw a glider through the bars in the cage.
Also-look into getting your baby a friend. They should not be kept alone, and I would be happy to help find a rescue or a breeder near you. Adding to all this, please get your glider on a good diet. Throw out your pellets and look into getting them on HPW, BML, Priscilla Price, or LGRS soup. There is a search engine up top for any questions you have. In the meantime, you can get them fresh fruits and veggies and either an egg, cooked chicken, or some fruit flavored or plain yogurt for the protein.
