I have one cat shine left to collect. The map shows an exclamation mark for where it should be, but each time I check the map it's in a different spot.

The moving cat shine may be on the floating island that circles around the map.
Head to the top of Mount Megameow, near where the Blue Toad is found. Equip a cat suit and wait for the island to come around. Once the island passes by, climb up and grab the cat shine.
