I love both cats and dogs. I really love spaniels/setter, irish wolfhounds, shiba/ akita inus and borzoi! My babygirl Aika is a black little schnauzer mix though :3
For cats i think siamese cats are super gorgeous. Oriental longhair cats are also cool (thinking of Pangur from tumblr user pangur-and-grim...) I dont know about that many cat breeds but orange and calico ones are are always very sweet. My partner is allergic to cats :'( so they are really interested in sphinx cats!
I don't know cat breeds that well to have a favorite. But maine co ons and Norwegian forest cats are pretty.
Dog breeds, I really like are chihuahuas, German shepards, and golden retrievers. Except I don't think I ever want to have a large dog again. After having a chihuahua for a couple years, I only want small dogs now. Besides Chihuahuas are better for my lifestyle than a big dog anyway.
absolutely a dog person bc they match my energy level after I've had coffee, but my favorite dog has to be an Aussie or Australian Shepard bc I love their mismatched eyes
