Oops I made another Cats OC. His name is Byron and he’s a Pollicle Dog (specifically a Beauceron). He’s like 6 or 7 years old, so he’s a mature dog, but he was still just a pup when The Great Battle happened, and doesn’t remember it. He lives with a human family so he doesn’t get to roam much, but because of his age and level-headed/cool demeanor he’s generally a well-respected Pollicle.
I imagine the Pollicles and Jellicles are sorta like begrudging allies. Technically at peace, but more out of need than want. Like siblings. He’s frenemies with my cat Hesperos and the two often run into each other when Byron is out on patrol with his human who works as a night guard.
