Truthfully I cannot remember.
Looking at dr. Google, there are apparently a relatively limited number of creatures that pass the "mirror" test for self awareness. Elephants, the great apes (bonobos, chimpanzees, orangutans, gorillas and humans (older than 18 months)), European magpies, bottlenose Dolphins, and Orcas.
Another item that led me to my conclusion was tool use. Various great apes have been observed using tools in the wild (including
spears for hunting) and so have members of the bird family
Corvidae (wiki).
Cephalopods are also very intelligent, although studies have been more difficult to do and hence may be suspect. Octopus use tools and have shown problem solving skills, and their brain-to-body mass ration is similar to the great apes (other than humans).
So, the question becomes, do we assume that our fellow creatures are "dumb animals" because they don't use a language we understand, or do we give the benefit of the doubt? More and more, I lean toward the benefit of the doubt.
