Both cats and dogs are great. Personally, I have cats at home (3). But dogs are great too and I'd adopt one if i had the space and time to proper care for it. Felines are just lower maintenance in that respect.
-Fantasy with means of magic and sword based feelings, i do prefer a bit of romance in stories
-Modern with again a fantasy feel
-Cut in anything with a bit of Romance and I can give it a try.
Dogs. I love cats but I cannot do the litterboxes! Dogs just make my days of anxiety nonexistent with their unconditional love. Nothing like being dog piled because they just wanna love you and make sure you are happy!
I like both, but I prefer cats. I find that a cat's personality, in general, is best suited to my own. They're independent, don't always need or want your attention, but they can be very affectionate in their own way. As a major introvert, this is the perfect arrangement for me.
