Yes, obviously.
I don't know what a soul is to you, but to me there's only one meaning of it that means anything at all, which is the presence of subjective experience, qualia. Is the thing a philosophical zombie, or does it have an internal life that it experiences as I do. If we define "soul" as some other thing I don't give a shit because subjective experience is the only thing that really exists.
Now, I know that I experience qualia. I'm not special in any way, so presumably things similar to me - other people - experience qualia, have souls. People, in turn, are hardly different from other animals. I mean, would a Cro Magnon have qualia? Would a gorilla? Dog? It's all a spectrum of life from forms of lower complexity to forms of higher, and I'm not convinced that complexity is even the deciding factor, other than that we can tell that qualia is, clearly, epiphenomena of nervous system activity, so perhaps things without nervous systems don't experience it.
I don't see there being any practical differences in animal behavior and human behavior to mark humans out as unique. Various animal species demonstrate emotion (including love, which can be outright proven for dogs and cats), social organization (ants even have proper civilization). Animals practice agriculture (ants and beavers), cook their food (bees), use technology (some crows), mourn their dead (crows and elephants), wage war (gorillas), organize into hierarchies of violence (chickens), learn (pretty much all of them).
The real interesting question is if plants, cells, and societies of animals have souls. (I think they do.)
