Ok lets say for the sake of argument OP is absolutely correct and somehow the entire world agrees. From tomorrow on keeping pets becomes illegal and all of them are set free, and not allowed to come back since that would make them pets again. And that results in a 100% chance of A LOT of them getting killed/severally injured due to a large number of reasons.
And while this is stretching things: in order to believe that keeping pets is immoral you would have to believe that the end result of those animals no longer being pets is moral. So OP do you believe the mass deaths/suffering of a large number of animals to be moral?
