People who have traveled with Norwegian airlines: do they weigh you personal item?

On all the flights I've been on no one has ever weighed personal items i.e. Hangbag, backpack, etc. I thought the weight limit for he carry-on with a lowfare ticket was 10kg but apparently thats a combined weight with you handbag. Do they actually weigh both? Also my bag is 2cm over the size limit do you think theyll notice?

How does putting a pet in airline cargo work, what's it like to do that?

In a couple months I will be shipping my cat through cargo on an airplane. So what's that like, what should I expect? Will they treat her like a checked bag? Should I put a lock on her kennel? Should I attach food and water bowls? I want to, but won't they spill? Anyone have experience with doing this? How'd your pet hold up? How does it work, how do you get them back?
