Slow Lorises: The Welfare Crisis of the World's Only Venomous Primate as Pets

Slow lorises are highly threatened by the illegal pet trade, with viral videos driving demand for animals whose welfare needs are impossible to meet in captivity and whose teeth are cruelly removed before sale.

Key Facts

Slow lorises (Nycticebus spp.) are the only venomous primates: they produce brachial gland secretions that combine with saliva to create a toxic bite used against predators.
Nine slow loris species exist across South and Southeast Asia; all are Critically Endangered or Endangered, with the illegal pet trade being a primary driver of decline.
Before sale as pets, the teeth of slow lorises are cut with wire cutters or nail clippers — an agonizing procedure performed without anesthesia that causes chronic infection and pain.
Slow lorises are obligate carnivores with complex dietary requirements including live insects, tree gum, nectar, and small vertebrates — impossible to adequately meet in captivity.
They are nocturnal, solitary, and cryptic — fundamentally incompatible with the human interaction demanded of pet animals; the constant handling in petting situations causes severe chronic stress.
Viral "tickling" videos of slow lorises showing arms raised are misinterpreted as enjoyment — the posture is actually a fear response, exposing brachial glands for defense.
International Primate Protection League and Little Fireface Project work on loris conservation and demand reduction in key market countries.

Welfare Considerations

Slow loris welfare in the pet trade is catastrophically compromised at every stage. Capture from the wild causes family disruption and transport mortality. Tooth clipping — performed without pain relief — causes immediate extreme pain and results in lifelong infection, difficulty eating, and slow starvation in many animals. The physiological stress of daytime activity forced by owners (lorises are nocturnal), constant handling, and inappropriate diet creates chronic welfare failure. Animals showing the "tickle" response in viral videos are demonstrating fear, not enjoyment — the raised arms expose brachial glands as a defensive posture. Slow lorises in private hands have median lifespans far shorter than their potential 20+ year wild lifespan. No amount of good intention compensates for the impossibility of meeting their needs in captivity.

What You Can Do

Never share slow loris videos that show pet lorises — sharing increases demand and funding for the illegal trade.
Report suspected slow loris social media content to TRAFFIC and the International Animal Rescue social media monitoring programs.
Support Little Fireface Project's conservation and demand reduction programs in range countries.
Donate to slow loris rescue centers in Indonesia and Vietnam caring for confiscated individuals.
Engage with demand reduction campaigns targeting slow loris consumer markets in East and Southeast Asia.
