The babies were hissing in the cage pouch and Belle was hanging out in the cube on the other side of the cage. Were they calling her?

Possibly. Sometimes Smoke does this squeak(bark) with a long hiss and kind of a "cry" when he's out looking for Zoey. It kinda sounds like the female's "in heat" noise, but different. He's a little weird though. They probably are calling out to her. Smoke barks for me and does that weird bark/hiss/call for Zoey.

Xena and Belle make that hiss bark noise at each other. The noise the babies were making was just a hiss. I was a little scared and took a look and i guess Belle wanted to investigate me so she went back to the babies. She somehow moved them back to the cube when i went out of the room.

This is the second time ive seen them and, once again ive forgotten to see if she has boys or girls or both. Lol, i want to know so badly so i can give them names but, im afraid to bother them.
