Cody freaked out completely this afternoon. He was standing on the back of my chair as he often does, when he suddenly jumped down, ran to the window and started jumping at it. He then ran away, knocking down a few things along the way, and hid for a few hours. When he came out of hiding, he looked very edgy and upset.
Most likely there was something on my patio. We have a stray cat & raccoons that come around occasionally, and there are lots of lizards.
