Just watched
Unlawful Entry again, and "Tiny" (Merv) figures prominently in the plot, and in my opinion does a fantastic job. I'm wondering what information there is about him? He's not listed on IMDb, but according to the NY Times he may have been in a pilot called "Claws" filmed at about the same time as
Unlawful Entry.

Cat actors usually appear in movies or shows and are usually not credited, and even if they are, their future life and fate is with few exceptions unknown to us. While we hope that they live out their lives well cared for and loved, who really knows? Merv must have passed some time ago, I only hope that he lived out his life with dignity.
