The welfare of animals used in pet food production is largely invisible to consumers. Improving pet food ingredient sourcing standards can extend welfare improvement to billions of additional animals.
Caring about pet welfare while ignoring the welfare of animals in pet food creates a moral inconsistency. The animals in pet food ingredients deserve the same welfare consideration as the companion animals being fed. Consumer demand for welfare-conscious pet food ingredients would extend animal welfare improvements into a massive production sector that currently operates largely outside welfare scrutiny.
