Unity c# destroy spawned prefab with mouse click

Question

I have a script to spawn cats at random positions in the game and when the user clicks on them they should be destroyed. I am having trouble with my script however and was wondering if anyone knew what was wrong with the raycast?

public void CatClick () {
            if (Input.GetMouseButtonDown (0)) {
                Ray = Camera.main.ScreenPointToRay (Input.mousePosition);

                if (Physics.Raycast(Ray, out RaycastHit)) {

                    Destroy(RaycastHit.collider.gameObject);
            }
        }

    }

Another way to do it:

 using UnityEngine;
 using System.Collections;

 public class CatDestructor : MonoBehaviour 
 {


     // Use this for initialization
    void Start () 
    {

    }

     // Update is called once per frame
     void Update () 
    {

    }

    void OnMouseDown()
    {
        // Destroy game object
        Destroy (this.gameObject);
    }
 }

Put this script on "cat" prefab and if you click on it, it will destroy the "cat".

Or you must put your code to update function like this:

 void Update(){
   if (Input.GetMouseButtonDown(0)){ // if left button pressed...
     Ray ray = camera.ScreenPointToRay(Input.mousePosition);
     RaycastHit hit;
     if (Physics.Raycast(ray, out hit)){
       // the object identified by hit.transform was clicked
       // do whatever you want
     }
   }
 }
