My cat is allowed to go in the fenced yard when we are home and it is light out. He has a prior injury so he won't climb the fence. There have been a few times I couldn't find him and I get all scared and worried. Yesterday I was calling for him, and he usually comes, but he was nowhere to be found. Finnally I dig out the treats, shaking them and yelling "Treats!" He comes out of the spot and cries to get one. Cats play a great game of hide and seek!
