:) Yep, you know what they say about curiosity and cats... and that holds doubly true when large snakes are involved.
When I knew I was moving into my dad's den, I changed the latches on my cages to the spring lock hooks to be safe, as he has two cats. Good thing I did so:

Suki got really really interested in 'that moving thing'. :) My snakes never struck the doors when she was around, but it didn't take her long to realize that those long things could be dangerous to her.
She was MUCH more interested in my skink. :) She loved to jump up on top of his cage, watch him move around, and would often bat at the door. Topaz just took it all in stride. :)
But yeah, I would always go with 'better safe than sorry' when cats are involved.
