I have a 4 year old tabby blind cat, so doesn't go outdoors. I always make sure I play with him regularly, but I feel the only toys I can play with him with are bouncy balls (he loves them, and is surprisingly good and running and catching them!), or dangly things. Obviously being blind, most typical cat toys aren't really suitable. Does anyone have any suggestions for other toys that might work for a blind cat? Just want to mix things up a bit for him .
