1. that sounds like alot. Do you have them on a proper diet?
I will give mine 4-5 mealworms every other day. They dont like dried papaya much anymore, so I give them about 2-4 yogurt drops sometime, or put the yogurt in the foraging cups.
2. we use fleece pouches, have to cut their nails about every 3 weeks so they dont get stuck on stuff. we did have small trash cans with lids from dollar store that they LOVED but they got very protective in them so we removed them.
3. take her to glider safe small darkish room, sit still and let her explore on or around you, whatever she likes. feed her a few treats. put hand in sleeping pouch so she can sleep with your scent OR put scented cloth in their sleeping area so they sleep with your scent. Put in closed bonding pouch keep with you for a few hours a day, talk to her.
5. I was told by a vet that once they hit adulthood they can not age them, only when they are small they can guess age by size.
6. We dont bond our gliders with other animals, some do, but I read that anything smaller then a glider is potentially food for a glider, and anything bigger is seen by a glider as a predator (eat or be eaten). It just seems to dangerous to try, specially with our dogs.
7. yes you should trim their nails. I think that is the only grooming that is really needed unless you have a sick glider, some have cleaned off bottom area after a poo. please do NOT wash your glider in water, ever.
