This question has been asked before Should a cats/dogs tag always be added to kittens/puppies questions?. I'm asking that now the site has grown and is developing that the accepted answer to this is no longer suitable. Can we revise this?
There's many questions that are specific only to when an animal is young and this would assist searching posts. The tags are what assists in generating search engine results. So if someone has an issue with a kitten they will search kitten, we only have cats. A search on posts with kitten as:question in it yields 296 results. With a tag search it will give better results in search engines like Google. (I'm trying to get some stats on this on Stack Exchange meta)
Should we break up these synonymised tags? What do people think?
