Despite it's appearance this is NOT the sturdiest cat toy in the collection.  None of my three felines are obese, despite being inside cats only - which is not to say they are scrawny runts either.  But when each of them in turn lies down on it and the Board collapses to a flat piece I'm guessing this is pretty fabric covering up cheap cardboard.  I've purchased better before and now know to stick to pet stores for real pet toys.
