At home, feather wands are a great toy. There you have only 'family germs' that each animal has already been exposed to. I like to make washable wand decorations, and here is a hint a little boy gave me at an adoption fair a long time ago:
Take the adjusting wand from a set of mini-blinds and make a pompom type decoration with narrow strips of fleece fabric, short pieces of ribbon and other textured yarn and string. Tie the pompom onto the wand and 'voila,' you have made a unique toy for your cat. When you need to wash the pompom, remove it from the wand and place it in a laundry bag made for washing lingerie...Enjoy 'fishing' for your kitties!
