Hello and thank you for downloading the Cartoon Cat asset. What you are seeking is a container for all the animations which are found as separate files. This container in Unity is called the Animator Controller. So you need to do the following: - Click on the cat fbx (project hierarchy) and from the inspector, convert the rigging of this model to Generic. They are Legacy in Unity by default. - Create a new Animator Controller and drag it to the model on the scene. Make sure the created Avatar Mask is assigned below the animator controller. If not, drag it from the project hierarchy to the "Avatar Mask" public game object within the animator controller. - Now you can drag and drop all of those animation files here. Define the initial animation and create a relationship between those different animations. The above steps are so easy within Unity. You need to carefully read and practise the following link: https://docs.unity3d.com/Manual/class-AnimatorController.html
