Rigging
With full controllers, it's easier to create postures and animations. The features are as follows:
CTR_Root controls the entire model, and its customized attribute Down_Left_Foot_IK_FK and Down_Right_Foot_IK_FK controls the non-seamless switch of the IK/FK of the legs.
Up_Left_Wing_IK_FK and Up_Right_Wing_IK_FK switch the IK/FK of the wings, which is non-seamless. CTR_Body_U controls the movement of the upper body, and its customized attribute Neck_Follow/No Follow controls whether the neck moves following the parent controller.
CTR_Neck controls the movement of the neck, and its customized attribute Head Follow/No Follow controls whether the head moves following the parent controller.
CTR_Eye_Blink.L and CTR_Eye_Blink.R control the winkle.
The toes and feather of the tail come with finer controllers which control more subtle details.
And more...

Animations
Loopable walking animation at 30 fps, frame range 0-26
Unlooped sleeping animation at 30 fps, frame range 0-290

Features
The model is in meter units at real-world scale.
To run faster, the fur is hidden with Render enabled.
The model can be rendered in the current project without cleaning up.
No lights or cameras.
The rendering time is relatively long because of a large amount of hair. If used in the background, here are some optimization methods:
Decrease the number of hair children, and increase the thickness of hair
Decrease the steps of the interpolated spine.
