Animals don't feel pain & don't
suffer the same as we do!
So this is a lie. And a generalised statement, that isn't true.
Not all animals feel pain and suffer the same as humans, but this is not a good enough reason to kill them.
Even if we find an animals that can't feel pain or suffer, let's grant them the right to life anyway! It's really simple, we don't have to kill them. So don't do it.
