Happy Tree Friends Fanon Wiki

Niya Katsumi (ニャー かつみ or mostly called as Niya) is a character of HTFF.


Niya is a light yellow calico cat with brown and dark brown markings on her body. Not else is known about Niya's appearance but she appears to have sharp claws that she exposes whenever she wants to. She also has fangs instead of buckteeth.

Niya is mostly known for being hyperactive all the time with her aggresiveness towards something. She's kind of a very friendly and playful person if someone could control themselves for their safety. She always jumps and pounces onto anyone whenever she meets them. 

As a cat, Niya possesses feline traits. She will go into full cat mode whenever she sees cat-related stuff then go play with it. She enjoys scratching something and even someone. She likes most of what cats like and almost acts like one during her normal mode.

If someone acts nice towards her, Niya will probably want to stick with them as long as possible. However, if someone acts bad towards her, she will likely do something bad to them. Niya appears to have many cats as her pets. Almost all her stuff are related to cats.

Aside from her cat-esque interests, Niya also has stuff that she really doesn't like: dogs and water. She will likely attack dogs or dog characters in sight in her cat mode instead of just angrily meet them in normal mode. She also would attack mice or mouse characters if she wants to. Her deaths mostly involve drowning and her own aggresiveness.
