I was going to get a baby female glider to keep mine company, but the other day he killed a young gerbil. I guess he thought it was food (he tried to eat it.) Usually, the glider plays very nicely with my gerbils, but when he got hold of a baby, he killed it too quickly for me to do anything about it. I am worried that he will either kill or be very aggressive toward a new glider. He is usually not mean. I don't want a hurt or dead glider. Do you think that pouch/cage switching will help prevent this? If she smells like him he shouldn't think she is food, right?
