Just had to add that I am glad to know that other people's kitties hide things too!! My cheapy phone fell to the floor and the back came off. I was busy and didn't get to it right away. A little later, I went to put the back cover on my phone. I could not find it! I knew that Callie was batting it around after it fell but never dreamed she would hide it. We searched the bedroom and rest of the house and have never found the back to that phone.
Good thing it was a cheap phone. Silly cat!!
