Two weeks ago, I started at a new physical therapist. For the exercise portion, I was required to bring slippers. No problem! I have slippers!

KH: No.
Me: What no? These are perfect!
KH: They will kick you out for being unhygienic and burn the slippers.
So, nothing for it, I must purchase new slippers. I found these:

My physical therapist ALSO thinks they are adorable.
However, with two cats, I knew the little balls on the sides were not going to last long. And sure enough, last week I found one on the floor and put it on KH’s desk. Tonight, Sophie managed to get BOTH balls off the other slipper, while still attached to the string.

And she was playing with them, sooooooo happily that m0053 noticed. And watched. And watched. And soon, he snuck up on her, reached out his paw, and grabbed them. Now m0053 is playing with them sooooooo happily!
So I went to KH’s desk, and got the other lone ball, and gave it to Sophie, along with her favorite orange ball.

And Sophie was happy again, playing with her lone slipper-ball. And m0053 noticed. And lost interest in his two-balls-and-a-string, and snuck up on Sophie and stole her one ball.
I gave Sophie the two-balls-onna-string. m0053 now wants those. I give Sophie the lone ball, m0053 snatches it away. No matter what I did, swapping balls, speaking sternly to m0053, spanking his butt, all were ineffective. The only balls m0053 wants are the ones Sophie is playing with. ALL THE BALLS WILL BELONG TO m0053!!!
Poor Sophie. She has no balls.
ETA: m0053 was playing with 2-balls-anna-string. I give lone ball to Sophie. He stops playing, and looks back and forth several times between his balls and Sophie’s. Before going to take hers. He used his one brain cell to CONSIDER it. *sigh*
