In light of the current Weekly Challenge, two questions have been asked so far about pets. These questions used a new tag, pets. We already have a tag animals. Why both? I think questions about pets should go into animals. Anyone disagree?
Aren't pets a special case of animals with their own particular set of issues?
I think the question really is whether there are likely to be a substantial number of pet-specific questions, and whether anyone will ever want to click on a tag to find them all (without having to sift through all the other animal questions). I think the answer to both of these questions is "Yes."
