The hardest part would be the rigging. You might be able to get away with Mixamo for that, but a recent Cats tool update added a decent base skeleton if you want to have your go at posing it and using Blender's rig tools.

Move the skeleton bones around in edit mode so it matches what you've made, then in object mode select your mesh, then select the armature separately, and use the "Ctrl+P" shortcut, then click on "With Automatic Weights" from the dropdown menu.
