animal=wellness is a terrific example of conflicting key usage [1] 
between "It is for ___ animals" [2] and "It is a ___ for animals" [3]. 
It looks like there's already been an effort to deconflict this usage, 
with amenity=animal_boarding now pairing with animal_boarding=* and 
amenity=animal_training with animal_training=*. Meanwhile, access 
restrictions use freestanding keys like horse=* and dog=*, and the 
hazard=animal_crossing proposal currently would use hazard:animal=* or 
hazard:species=*. [4] If these "It is for ___ animals" usages are out of 
favor, then there would be no conflict in adopting highway=path 
animal=yes cow=yes or animal=path cow=yes for a cowpath.

Regardless, informal=yes seems especially appropriate for these 
animal-made paths.
