What is cat snails?

As an AI language model, I couldn't find any information about "cat snails." However, there is a species of snail called "Cat's Eye Snail" which is named after its unique, thickened, and reflective operculum that resembles a cat's eye. These snails belong to the Turbinidae family and are native to the Indo-Pacific region. They are commonly kept in aquariums and are prized for their attractive appearance and ability to keep the tank clean by feeding on algae and detritus. They are generally small in size, ranging from 1-2 inches in length, and have a spiral-shaped shell that is usually adorned with patterns or colors.
