Be carefull!!!!!
My cats love the machines too, until one figured out he could open the coin door.
Long story short, I traded my Kung Fu Master, then found our THREE days later my cat was inside!!!!
Looked for the friggin' cat everywhere and he was 50 miles away in Video Dans garage!!! grrr.
Break them of that habit quick, make them afraid of the machines.
I scream at my cats when they go near them now lol
