I don’t know of anything commercially available, but how about using your cell phone on a selfie stick? Check out amazon.com and B&H for ideas.
Or, if you’re a do-it-yourself type and want to use your video camera, make a “monopod” from a ski-pole or similar stick and an “L” shaped shelf bracket. Shorten the ski-pole to a convenient length, bolt the shelf bracket onto the bottom of the pole, drill a hole for a 1/4-20 bolt and fasten the camera to the bracket.
Your main problem, of course, will be getting the cat to cooperate! Good luck with that.
