Implicating kitten -> cat.

Reason: Young version of cat.

Similarly puppy -> dog.

(Hope I haven't done this the wrong way around, again)

To be honest, I don't even think that distinction really needs to be made.

Whenever I see a post with either a kitten or a cat, I just tag it as cat anyway. And given that kitten has such a low tag count, I don't really think an implication should be made.

Perhaps just an alias instead?

I thought this was done months ago (forum #23676). A certain now banned-for-a-year user went around separating kitten's & puppies from their respective species.

I'd support the implications. Young cats and dogs do tend to have a fairly distinct appearance from adult ones; same with most other animals, but that is another matter.

Well, I'll do the implication because it makes sense. Whether or not we need the tags is a different question that can be resolved separately - but assuming we keep them, the implication makes sense.

I don't see a reason to squelch puppy or kitten. If they are obviously young animals there isn't really any reason not to keep them distinct. The implication is obviously a good idea though.
