- Honestly I feel like cats don't have as much personality. After working with hundreds if not thousands of cats in rescue/vet med, they boil down to a couple personality types. And there's nothing wrong with that; if anything, it typically makes them even better home companions than dogs.
But I feel like dogs are better at being both a companion AND a hobby at the same time. Bikejoring, dock diving, lure coursing, barn hunt, agility, conformation, disc, fast CAT, obedience... there's almost no end to the hobbies you can try with a dog (if you pick a dog that suits what you want to do at least). For me that's more fun. And if I just wanted a cuddle companion I'd probably still choose a toy breed; but I can see why others would choose a cat!
