Catgirls, also known as Nekos (ネコ, cat in Japanese), are an intelligent species of cat-human hybrids that live alongside humans in the Nekopara universe. Catgirls physically resemble humans with feline ears, slitted pupils, a tail, and occasionally a cat-like mouth.
Catgirls were once left homeless and living in the streets, but now they are domesticated by humans and aren't allowed to go anywhere by themselves without their masters unless they have a bell.
Unlike real-world cats which are true carnivores, catgirls appear to be omnivorous as the Minaduki catgirls have been shown eating various foods throughout the visual novels, including sweets and tea. A running gag throughout the VNs is their preference for fatty tuna.
Generally catgirls can behave much the same as humans. They have the ability to learn, communicate and having complex emotions. Maple for example is shown having experience with emoticon texting, and began learning the guitar in Vol 3. She also detested the phrase "catgirl" as she viewed it as a term that paints her as a lesser species.
On the romantic side of things, catgirls are also stated to be more honest about their feelings.
Having cat-like traits however means that younger catgirls are often prone to some of the habits of regular cats, including the desire to hunt small objects, tails sticking up when happy, and giving in to food temptations. They can be taught to ignore these desires to some degree, as shown when the Minaduki catgirls tried (and failed) to show their restraint as a result of getting their bells.
In general catgirls mature much faster than humans, reaching sexual maturity at around a year - the youngest so far being Chocola and Vanilla at 9 months old, with all the other catgirls having been stated by Shigure to have gone into heat before Vol 1 and working it off with excercise. Likely because of their rapid growth, they must pass a social skills test to earn their bells and their independence - although Cinnamon states only 1 in 10 catgirls ever pass.
It can be assumed individual catgirls of the same breed develop differently like humans, though it has been shown that there are clear differences between breeds. For example, Coconut is a Maine Coon at 1 year old, while Azuki is a Munchkin Cat at 3 years old, with the former appearing much older than the latter in both body shape and build.
In the Nekopara universe, relationships between a human and a catgirl are not uncommon, and a catgirl in such a relationship is referred to as a "catpanion". Catgirls cannot produce offspring with humans, though their physical similarities with humans mean they are still capable of intercourse.
