this a random thing? Practically no hope to ever find out ... ;-(.

Carol responds:

I don't know the answer, and I'm not sure that JKR does, either,
considering that she sometimes seems to mix up the two, as here
(Snape's/Lily's Patronus form matches James's Animagus form) and in
some of her interview responses.

I can't think of any character besides McGonagall for whom we know
both the Animagus and Patronus form, for one thing because there are
so few Animagi. Would Wormtail's Patronus (and he must have had one if
the original Order used them to communicate) have been a rat?
Charming. (Don't get me wrong; I like pet rats. But Peter is a common
street rat.) Would DD's Animagus form have been a Phoenix? Was Sirius
Black's Patronus form a dog? We just don't know.

However, we do know that a Patronus is a kind of protective spirit,
sometimes representing someone else (DD's represents Fawkes, if Fawkes
counts as a someone; Harry's Patronus represents James, Snape's
changed Patronus represents Lily; Tonks's changed Patronus represents
Lupin). I can't imagine Tonks's Animagus, if she had one, being a
werewolf, or Snape's being a doe! Rita Skeeter's, however, might well
be a mosquito to match her name and he beetle Animagus (a mosquito
Animagus probably wouldn't survive very long; it would be squished the
moment it landed on someone's arm!)

Carol, who thinks that Ron's Animagus form would be an otter, to match
Hermione's Patronus
