It depend on what "level of consciousness" do you refer to. Most animals when they see themselves in the mirror don't even recognise that its their own reflection. Meaning that they are not self-concious some research would suggest. And another thing is that animals mostly live by instincts, which I think dont "use" consciousness to help them survive. So I'd say I do feel like they are not all that concious at all. I liked the question and would love to see your take on it. :)
