Can't play ball with my cat

[LadyTaelia Resident]

Thank you very much. I tried the cattery suggestion and my cats will play with me once I've done that.
Only thing is when I do play with them again, they play for a short time and then come back to me saying
the same message of Could not find object KittyCatS Toy in which I do have to send them to the cattery again to
fix the problem before I can play with them again. It's not a huge deal knowing there is a way to fix the issue
though. Your suggestion was one I did not know I could do as I'm still fairly new to raising KittyCats.
