It’s ok for animals to be able to see the order and the kind of powers that we have. There are no animal species that can communicate to humans exactly what we look like and that is the reason why we are not worried about being seen by them. We actually enjoy spending time around several animals because they are completely loyal to us and unpredictable to humans. The reason for this is that we can communicate feelings and even special commands to them to keep them from becoming anxious and from being violent.
We could easily pet a wild lion or swim in the ocean with a very powerful and hungry white shark and we would not have to worry about a thing. This is why we allow animals to see us and we do not mind having them around. They are better companions than most humans after all.
