If it helps, they don't NEED to eat animals to survive, in case that's a point of contention between you two.
The kid could grow one as just a neat looking plant.
They are a little sensitive, though, so hopefully your kid wouldn't be too upset if it doesn't work out.
@volkris he's not vegan, just me - it's just weird, it's a weird plant! He likes them and they're native here, there's just something so weird about it.
Gotcha. But it can be a vegan fly trap just as you're a vegan human :)
Anyway, yep, I personally like having the weird... errm... eyecatching plants around.
It depends on the aesthetic.
Exactly.
Like I said, some of them can be a little temperamental when it comes to getting just the right amount of light, and I think sometimes tap water might be bad for them, but bugs are sort of a special treat they don't really need to survive.
