Luv, when my cat had a litter of five, I fell in love with each one of them. I can’t have a cat now, because my SIL and Granddaughter are allergic to cats. :(
But - to entertain the kittens, I went to the fabric store, and got several yards of heavy elastic thread. I attached a pompom to one end, and attached the other end to the ceiling (yes, with a nail)!
I kept the pompom just high enough that they would have to jump a little bit to hit it - and it would go flying all over the room. It entertained them for hours!
I cried, when I found good homes for each of them....
LOL! I am almost tempted to try that, but anywhere it flew it would hit something. :)
