My cat, Mr. Pickles, loves the natural colored whoo balls! He’s very picky about his toys so that’s wonderful. The natural color is just enough that they look like they may possibly be a mouse! I so appreciate it that he likes to play with them. Thank you very much. I will buy other stuff in the future. I just don’t know what yet but you’ll see an order for me soon, again thank you and I love your products bye
