Most times my furkids will play with anything we give them and that would probably unused paper bag, empty containers and strings. However sometimes, they choose what they want to play. That can be anything from my hanged towel to my vitamin bottles. At times we don’t even know what is missing till it’s time use them. Anyway cats will be cats but wouldn’t it nice if one day out of nowhere they start playing with an eisenhower dollar? hahha.. kaching!
