Yes.
Rationale?
Venus fly traps are not animals.
But they eat animals.
Fungi are more closely related to animals than plants. Are they vegan?
I think you need to look up the definition of of “vegan.” It’s not based on what your food eats: you can’t call eating a grass-fed cow “vegan.”
Fungi is also not animals.
If a plant has to eat animals to survive then that plant is a product of animal suffering. Thats why vegans don’t drink milk or eat eggs too. So if that’s the definition of vegan that someone subscibes to then the flytrap is not Vegan.
That’s not the definition of vegan. The definition of vegan is a person who abstains from animal products. Plants are not animal products.
Eating a venus flytrap is also removing a plant that eats animals.
There are plenty of vegans who would tell you they abstain from any products of animal suffering, otherwise they would use products that were tested on animals. Just because you test lipstick on animals, doesn’t make the lipstick a product of animals, its a product of animal suffering. Your definition is not the only one and doesn’t exclude animal tested products, which many vegans go out of their way to avoid.
