My spouse and I have a Maine coon mix that is exactly like that. He plays fetch, has an exercise wheel that still doesn’t tire him out enough to let me freakin sleep in the mornings, loves water, and even ‘wags’ his tail so much that it’s beefy, just like the rest of him. All domestic cat, no need to hybridize them with wild cats and create at least 2-3 generations of animals that can’t happily live indoors before you get something approaching a pet.
