Hello.
I'm an Evo and like both, to be honest. But, if I was forced to choose between the two, I would have to go dog. I love cats and grew up with a couple of them, only to have both of them runoff.
The greatest reason I do not have a cat as of now is because of the vast amount of birds that live around my house. Swooping through backyard to backyard, looking for food, nesting in and around trees in my yard, this cat could possibly kill many of them.
I recall watching an Ultimate Guide edition on the Science Channel about cats. The house cat was the most successful predator of all the cats. They kill, if I remember correctly, between 3-5 billion birds annually in the U.S. alone.
To my liking, my dog is rather indifferent to birds. However, I'm sure the simple solution would be to keep my cat indoors more often.
