Jeni,
I'm glad you came here for info. Gliders are not easy pets and they have special needs and desires unique to them.
First,
diet. You didn't mention specifically what you feed her, but pellets as a
diet, even with fruits and veggies added, is VERY unhealthy for gliders. I say this because
mill breeders are famous for advertising the use of leashes, and they are also famous for saying all gliders need to surive is pellets and a slice of fruit - both GARBAGE. Gliders need a spedific amount of calcium (and at the same time a specific amount of phosphorous), they need a certain amount of protein, they need other vitamins and minerals that pellets just do not come close to providing. Click on the word
diet and it will take you to a list of recognized and approved
diets for gliders. These "staple"
diets are to be offered with fruits and veggies, bugs like mealies (if your gliders will eat them, mine won't), and treats in moderation.
Second, quarantine for the new glider. You can't just put these gliders togeher, both because the new one might pass something on to your original glider, and because honestly it'll stress them both out. 30-day quaratine with the new glider is neccessary....separate rooms, separate cages, separate
toys, everything....separate. Wash your hands thoroughly and change your clothes between handling gliders. During this 30-day period, you'll need to get
vet checks with fecals on your new glider - once at the beginning of the 30 days and once at the end to check and see if this new glider has parasites (which have 2-3-4 weeks life cycles and shed in the feces, hence doing 2 fecals).
Third, intros. In the
bonding & Relations area, there's a ton of articles of introductions and the way to go about it. When you have 2 clean fecals after 30 days, you can start swapping their
pouches and
toys to get them used to eachother's scent. Intros need to be done in a neutral area, like a tent or bathtub. Separate them immediately if "balling up" happens aka fighting.
That's the short of it. Welcome and ask questions all over the place - there's alot ot learn!
