Animals suffer for the same reason that big rocks break into little rocks. It’s part of the mechanism, the mechanical action, of the universe, which was made entirely for our benefit.
The only suffering that IS actual suffering is the suffering of persons.
Animals are not persons.
What seems to be animals suffering is merely “rocks banging together”.
When we can alleviate the (apparent) suffering of animals, that “suffering” was put there so that those persons who could relieve that “suffering” would be able to practice “relieving of suffering” without having to have actual persons suffer.
Any questions?
