It's very interesting. Here's some info.

Adult slow lorises range in size from 21 to 38 cm (8.3 to 15 in), depending on the species, and weigh up to 2 kg (4.4 lb). The tail is a mere stump, and the forelimbs and hindlimbs are of roughly equal length (quadrupedal). The short, thick fur can have a variety of colours, but most common is reddish-grey with white undertones. They have well developed opposable thumbs, which they use to grasp and hold branches, and a very flexible back. A specialized arrangement of blood vessels in the wrists and ankles (rete mirabile) prevents muscle cramps and allows the slow loris to cling for extremely long periods of time. They have a grooming claw on one foot. Their eyes are large and point forward and also upward, and color vision is minimal. Their ears are small and nearly hidden in the fur. They are generally built stronger than the slender lorises, and possess a strong sense of smell.

Also... they produce toxin that mixes with their saliva. They'll lick their babies before leaving home. Cool, eh?
