When you're self employed you have to wear a lot of hats, and I've never owned a videographer hat before.
This means that I also have never owned the equipment, worked with lighting, or had access to an assistant who could wrangle the cat models while I filmed. My results are painfully amateur, but these little films will give you an idea of how my cats use their Cat Ball for play time while also demonstrating the device's physical properties.
This video shows the same cat in a Jumbo Cat Ball. The music is annoying in this one.... sorry!
This particular cat weighed about 9 pounds at the time. He's got thick fur on a petite build.
