On Superuser we have a pretty well established process for this, though there's a significant need for moderator and user buy in.
We use the "community-faq" tag (And something like this would fit in there well as well) - and typically open up the process with a meta post like this one, and a certain degree of consensus.
Once that's done, a good answer covers a broad range of information on its own - as well as links to useful resources. Its also handy as a way to close other questions with the same topic - which is why consensus is handy.
What works well for SU might not work as well for pets - so I'd probably suggest seeing what the local mods, and the community think.
Here's an example of one I did on SU - I probably could have CWed it (can't remember why I didn't) but I've tried to tie in as much information as possible both from the site and off in my answer.
I've created the tag, and prepopulated it with a tag wiki excerpt and a few guidelines tailored to pets.
