Oh, Felidae wasn't exactly a tear-jerker but the excessive bloodshed of innocent animals (female cat is decapitated, pregnant cat gets slashed, dead cats used as marionettes) basically broke my litte heart when I watched this at 12-years-old.
1) Lion King. 2) HP and the GOF- Ending ... poor cedric. 3) HPand the OOTP- Ending. . Sirius, no!
I am also a big fan of: Phantom of the Opera, High School Musical, Harry Potter, Disney in general, Days of Our Lives, musicals in general, Dr. Seuss in general and the Grinch.

Hachi: A Dogs Tale Fluke The Fox and The Hound Two Brothers
Now, if you cried at Marley & me, I recommend watching Hachi. I didn't cry at Marley and Me, I cried for like an hour at Hachi. It's by far the saddest movie I've ever seen.
1. Hachi 2. Marley and Me 3. Aviator 4. Titanic 5. Soul Surfer 6. Bridge to Terabithia 7. The Lion King 8. Bambi 9. Old Yeller 10. The Fox and the Hound
EDIT: Also 'Shindlers List', we watched some of it at school and I had to go out of class cause I was crying so much.
TLK (duh) Hunchback of Notre Dame (God Help the Outcasts never fails to make me sob) Bridge to Terabithia Harry Potter and the Deathly Hallows part 2 Pan's Labyrinth
There's probably more, especially if you take the movies that aren't sad but have one or two sad scenes into account as well...for example Narnia always makes me sob at that part when Aslan sacrifices himself..and I cried like a baby when Eugene died in Tangled. I'm a very emotional person generally.
