When switching from using two screens to just one, you might notice that the Pet Palette sometimes appears off-screen. Alternatively, it may open in an unusual position, making it difficult to locate.
Solution
You can control the positioning of the Pet Palette. It can be configured to follow your cursor as you move around the screen or be anchored to a preferred location.
You can set these preferences here in the Options > Work Environment > Dialog Boxes and Palettes.
