As you can see, they're nothing much. The cotton is Sugar and Cream that was leftover from a purse and I picked up some hemp twine to play with for more "chew" oriented toys. I made a mouse before and they barely play with it. I was hoping the large bean shaped one would be large enough to fight with, but they haven't taken to it at all. Maybe a finer natural fiber would work. Sisal or twine will probably be too heavy. I'll probably try some different shapes too. Calliope likes to wrestle with things so I may have to make a large pillow like toy for her. Perhaps a knitted toy would be more to their liking.
