Without rape, most animal species would go extinct

I wouldn;t be too quick to rule them out.  There may be differences between our concepts, but that doesn;t mean that their concepts aren;t concepts.  

I;d refer to the difference between whatever concepts we hold as a reason that animals may not be moral agents, rather than their lack of concepts..because I struggle to make sense of the claim that animals lack ideas or general notions or intent or plans. They express these things, frankly, in alot of the same ways we do..and we also have a habit of expressing ourselves with claw tooth and hoof, as it were.

We're not really different in those ways, even if there is some difference in our moral agency.

Basically every species if cat scratches and claws at each other, they also go into heat for those forays. I don't think you could classify it as rape, it's just how cats breed.

I think the idea that animals have a concept of consent is human projection. Animal mating works way differently than humans. Way way differently.
