What is it about?
When people discuss animal welfare in pet care, attention almost always falls on the pet itself. When live vertebrates (like mice) are fed to captive predators, strict ethical debates and care standards usually apply. However, billions of feeder insects—such as crickets, mealworms, and cockroaches—are bred, shipped, stored, and fed live each year with almost no animal welfare oversight. This review paper argues that the sharp distinction between how we treat vertebrate prey versus insect prey is no longer scientifically justified. Recent research suggests that many common feeder insects possess sentience and the capacity to experience pain or distress. As a result, the author advocates for a precautionary approach to feeder insect care across their entire lifecycle.

Why is it important?
Fills a Major Ethical Blind Spot: While the welfare of live vertebrate prey (such as mice and rats) receives significant scrutiny and regulatory attention, the billions of feeder insects sold globally each year have remained almost entirely invisible in welfare policies. This paper is among the first to directly challenge that disparity. Capitalizes on Cutting-Edge Science: The review builds on a recent surge in neurobiological research establishing that many insects possess sentience, central pain processing, and complex decision-making. It grounds its arguments in modern benchmarks like the New York Declaration on Animal Consciousness. Evaluates the Entire Supply Chain: Unlike traditional discussions that focus only on the moment a reptile eats an insect, this work evaluates welfare risks across every stage of the insect’s life—including commercial breeding, transport, retail holding, and home storage. Addresses AI-Generated Pet Advice: It is uniquely timely in examining how modern artificial intelligence and large language models (LLMs) provide pet husbandry advice, highlighting how AI can inadvertently perpetuate "folklore husbandry" by omitting insect welfare and alternative diets.
Perspectives
Unpacking this topic was both challenging and rewarding because it touches so many moving parts—from neurobiology and supply chain logistics to modern AI chatbots giving pet advice. The way we treat the smallest animals in our domestic environments says a lot about how our understanding of animal welfare is evolving. I hope readers find this paper thought-provoking and that it opens up fresh conversations about what responsible, ethical pet keeping looks like in the 21st century.
