I prefer to roleplay as non-feline/canine animals, so about 50% percent of my characters are on the feline base, and 50% on canine.
When it comes down to how many actual feline or canine characters I have (that are actually feline/canine, not horses, bears, rhinos, aliens, parasitic robot things etc), I would say I have a few more canines.
And probably 100% of those are domestic dogs. I absolutely love the huge variety you can have with just that one species.
However I have jaguars, lions, domestic cats, and a tiger as well. So it's pretty close to %50 feline %50 canine.
