While we were re-doing our bathroom I came across the perfect cat toy. The toilet bolt caps!! Marbles kept stealing them and batting them all over the house. He would pick them up in his mouth and carry them everywhere. I ended up going back to Lowe's and buying him his own to play with.
You can find them in the toilet "fix-it" section at the home improvement store for around $2. Perfect stocking stuffers for your cat!!
