Thanks to drugstore's compelling cat evidence she shared with me, we now know these pics from the Tendril Tales video and from the I'm Less Here video are both of Hope's cat Herman. I found a site that turns negative black & white images (with colours reversed, as these cat pics originally appeared in the two videos) into positive ones, making Herman's screenshots much clearer now! Although these are black and white screenshots, they pretty much show Herman's colours as he's a grey with black stripes tabby with small amounts of white on him, particularly around his mouth and under his chin. I'm pretty sure many Hope and Mazzy fans couldn't care less about Hope cat-trivia, but it's fascinating to me, and hopefully to a few others!
