The tag alias #59175 puma -> cougar has been approved.
Reason: These two are different common names for the same animal, which also, given the amount in each tag, look to be pretty equally used around the site. The difference is 'puma' doesn't have any of the implications.
EDIT: The tag alias puma -> cougar (forum #239) has been approved by @NotMeNotYou.
