- Slow loris are nocturnal animals. Therefore, being in a well-lit room is incredibly uncomfortable and can cause aches and pains.
- Slow loris cannot express natural behavior in captivity. In the wild, they travel long distances at night to find food, which makes being kept in small cages extremely cruel.
- In the wild, slow loris feed on complex fruits and insects, and their owners often find it difficult to meet these special dietary needs. This can lead to obesity and other serious health problems such as infections, pneumonia, diabetes, metabolic bone disease and malnutrition.
- Slow loris have a poisonous sting that is harmful to humans. Usually their teeth are severed, but if their teeth are still intact, they will mix the venom secreted by the glands in the upper arm with saliva to provide a toxic bite. This may cause anaphylactic shock and even death in humans.
- In many countries, keeping slow loris as pets is illegal. Most countries/regions have regulations prohibiting the purchase of exotic species (including slow loris). Whether any slow loris is legally kept as a pet is very rare.
- The slow loris are in serious danger of extinction, and the biggest threat to survival is the illegal wildlife trade. Keeping slow loris as pets will encourage trade, which will bring these extraordinary animals closer to extinction.
- They use urine to mark their territory, which makes them smelly!
