All of the cat toys I buy are very uninteresting to my cat. One day I found out that my cat love these cheap stuffed animal mice from Ikea. They're about .99 cents and I have 5-6 of them. My cat Mishka finds where I hide them and plays with them a bit and later delivers them to his kill zone (under neath my bed). It's also Olive's favorite toy (my Boston Terrier).
