Cat owl

The cat owl lives in both the Earth Kingdom and Fire Nation, primarily in the forests, and also has been seen for sale in a Ba Sing Se pet shop. Its natural prey are mice and other small rodents. Its distinctive meow-hoot is one of the most bizarre sounds in the animal kingdom. Superstition has it that running across a cat owl is bad luck.

Anatomy
A cat owl is a falconoid and has the head and tail of a cat, along with the wings and body of an owl. Its head, torso, and paw like talons are covered in fur, which is dark slate gray on its dorsal parts and creamy white on its ventral parts. The feathers of its wings and the tail, which is wavering and feathery, are also dark slate-gray. Its eyes are commonly seen as green.

Connection
Its body's coloration as well as facial appearance create an image of a great horned owl. Coincidentally, the real-life great horned owl is sometimes nicknamed the "cat owl". The cat owl has a tail, also furred, that is feline. Not quite coincidentally the Chinese word for owl (猫头鹰 Māotóuyīng) literally translates into "cat-headed eagle"
