This is super cool... I thought a while about how to DIY... could paper mache form around a ball and then pop/remove it, just would have to be a strong cast. Dollar tree has plastic chains around Halloween... box could be anything... If we ever get a cat, or small dog for that matter!
“No one is born hating another person because of the color of his skin, or his background, or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love, for love comes more naturally to the human heart than its opposite.” ― Nelson Mandela, Long Walk to Freedom
Harold doesn't entertain often in his 'boite de chat maison' (aka cat box mansion), but when he does ... he does it with style! It's all ya can catch Aquarium Sushi Hors d'Oeuvres, fresh kill mouse-kabobs 'n every feline's fav game after a few milk shooters ... 'bob for toona'
