There was going to be a sequel to this film based on its ending and appropriately titled "Cats", but when it flopped at the box office, production on the sequel was cancelled.
I and several friends were students at Southwestern Community College and extras in film Dogs. I was pleased to be an extra and found the filming intriguing. We appeared several times on the campus shots. Some of the scenes were shot on my street. I have been unable to find a copy of the video.
