Ok, so I had to move the fridge a little today to rescue Oliver. He was really after a toy that he'd pushed under the fridge. In the process of freeing him from his jam between the wall and the fridge I found 5 of his toys under the fridge. All of them related to how he likes to play fetch.
We'll see how he likes the 50$ worth of cat toys he got today.....a cloth tunnel and a mouse under fabric/circular pounce thingy. I hope these keep him from tossing toys under the fridge that's for sure!
