Interspecies

I suppose there's a reason individuals in a species go along with others of the like. Squirrels with squirrels, lizards with lizards, owls with owls. They have more in common, more possibilities. If an owl and squirrel thought they could be together, and the owls takes flight, the squirrel is left looking up at the other so free. A ground-dweller would have more in common with another ground-dweller; and the same goes for those who can fly. It would be unfair for the squirrel to cause the suppression of the cultivated abilities of the owl.
