Slightly larger than the MIni Fidget series, but still small enough to fit in the hand, the Themed Fidget series is designed to suit the often very strong interests of people on the autism spectrum by theming everything on that fidget around a particular theme. It has been designed with autism and ADHD in mind and packs as much movement and texture into the least amount of space. There are no separating parts, so no choking risk. This version is shaped like a cat's head and has four sections, with a mouse, bird, fish and cat's head shaped piece that can freely rotate. Great fidget to keep fingers busy and minds free.
