2-pk contains 1" and 1½" diameter balls.
"NO THAT SPECIAL"
My cat did not like this, just stared at them. Like cough drops in wrapper better to throw around and play with.
My cat loves these she bats them all around the house. Sometimes I will find them across the house. They are light and made well.
Our cats love these toys. Instead of just batting them around like regular balls, they use the loops to carry them around with their mouths, and to throw them around the room. I like that they rattle instead of having (sometimes annoying) bells. Highly entertaining for both cats and humans!
