I recently bought to young gliders and the previous owners fed them dog treats. They are called fruitables made by vet science. Are they safe for gliders? My other question is hamster balls. I watched another owners video and she said no because the slits could catch their small foot. Anyone else have say no or are they ok?

Its not so much their small feet, but their long and thin nails can go throw
the holes and get ripped off. ugly and must be painful.

I use yogurt drops, sugar free dried papaya at pet store, dried
mealworms and live mealworms as treats. I would worry dog treats might
have to many unwanted extras or chemicals.
