I only started growing carnivorous plants last year but up to now it seems to be surviving. I also have a sundew and a venus flytrap. I wouldn't say they are difficult but they can only be watered with rainwater and not be allowed to dry out in Summer. They require a resting period through the winter like other plants but I'll know better in Spring.
This is the pitcher plant - not a very good photo though, Sorry.
You can just about see the fly on the left that it's about to catch.
