I see some of the loops on cage sets (on the ends of pouches, hammocks, vines etc.) are made of fleece, some of ribbon, and some of elastic. Are they all safe options?

I have used ribbon and elastic. But i noticed snags where their nails got caught. So now I only use fleece. The fleece loops or ties last longer too. Once the snags start they become more hazardous. Toes can get caught and cut off circulation.

I use rex lace and fleece for stringing toys.

Thank you! I shall stick with fleece.

I have been sewing for sugar gliders since around 2003. I agree with VBclick, fleece is by far safer. I have seen gliders get nails and toes caught in elastic. The idea is nice, but it isn't functional for sugar gliders. Ribbon usually doesn't last and it snags on nails (and for whatever reason my gliders always seem to destroy it!).
