That's a good site but I think the thread should have a different title or at least an intro for the link in case someone tries to search for the kind of information.
I'm not a fan of Sandra Todd... and we really can't add her info here without permission.
But I think a link is ok. The link is how to care for an elderly rat. Now that I think about, it would be a good thing to have here, might write one myself, using the info we have here from our own members.
