I have some...problem kitties who are just fascinated to death with my litter robot; However, their fascination led to them chewing the buttons right off the machine after owning it for less than 2 months. I was beside myself thinking how I would fix the panel. Luckily, I came across this site & am so thankful I did. I received the button panel in a decent amout of time and it was super simple to switch out what was left of the old button panel & replace it with the new one. I also applied some bitter spray to this button panel! Lesson learned!
