the cat mouse thing that tore padmes shirt

roar!

That is a Nexu (I've had to fight them on Star Wars the Old Republic), and according to the original script, it ripped her entire top off, not just a sleeve and the lower half. Of course, since this was a family film, they couldn't do that, so they settled for the alternative.

It was certainly a scary creature, nay monster. The other two were a lot less memorable. But for Padme to be faced with that horrible thing was surely traumatic for her.

That is right 😄
