We have no canon examples of a person using a Vanishing Charm to make something disappear and come back later. We have accidental magic (which does not appear to follow normal magic rules, as I note elsewhere), we have objects being Vanished and never seen again (including all the entries in the Wiki), and we have Vanishing Cabinets, which we have no reason to believe are the same thing as Vanishing Charms.
To assume that "a thing disappears by magic" = "use of Vanishing Charm" is as spurious as to assume "a thing gets killed by magic" = "use of Avada Kedavra".

Which is more likely, that the Vanished animals follow the trends already observed for all the related magics, or that Rowling makes an exception for the animals and Hogwarts is a charnelhouse?
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
