To lighten the scene, reduce the number of iterations from 2 to 0, and increase the render iterations from 0 to 2.

For correct rendering of fur, go to "Rendering" - "Environment" - "Effects", click on "Hair and Fur" and opposite "Hairs" select "geometry".
In the "Hair and Fur" modifier, in the "General Parameters" section, drag the mask from the "Maps" folder to the "Scale" column. Each object is assigned its own mask with a logical name, for example, "Pillow Cream Hair and Fur Scale mask".
Note: There is no fur in the fbx file.
