Despite being a tall mass of blonde curls and firm muscles, Wayne's nature is actually very gentle toward animals, especially little critters that ends up trapped in his office or in some corner of his flat.

This soft spot toward animals is actually seen as a sort of defect in his personality for a Warrior of Lugh like him (usually these warriors they are much more serious, cold and composed. Not cruel toward other loving creatures, but mostly disinterested toward them) but he doesn't know any of that (and probably he wouldn't care as well)
