Most animals don't recognize themselves in a mirror. Yet, they obviously can recognize another member of their species. E.g., if you have a cat for a pet, and introduce a new cat into the mix, both will likely do more than just notice each other. Same with dogs. Cats, dogs, et al, are able to tell the difference between cat, dogs, et al. Obviously, this ability to distinguish members of your own species works out nicely, especially for breeding purposes. But, how does it work? How does the old cat in the house know that the new addition is also a cat and not a small rabbit?
