The model consists of two parts:
It can be printed without supports if you orient it like shown in the picture.
The connection between the handle and the shovel is a tight fit. Optionally it can be glued in place with some ca- glue.
The cat inlay can be printed in a different color (2 layers on 0.2mm layerheight). Just load the models for the handle and the inlays together and set a different color for the inlays.
