My mother saw this on tv: [link]
And I thought it was so brilliant that I decided to get one. Cats are designed for hunt, not sleeping and eat all day long. Even though my cats are old, they need exercise and stimulation. They are both female, one is thirteen and the other one is 11 years old. The oldest one already know how to use it but the other one is still looking up for me to give her foods (just like she did for the last 11 years). She is a spoiled cat so that's why it's hard to change her.

This thing was designed for treating cat obesity and mental health problem. My cats doesn't have these problem, but anything that can make them happier is good enought for me. Even my dog has his own special bowl.

I'll will upload videos of my pets in a couple of days...
