Material Changes through code not working...

I am creating a character creation scene, and my cat species can have its paws, eyes, and pelt color changed through C# code. Unfortunately, even though nothing is parented, the two back legs never change color (they are all separated for animation purposes of course, so it is not a UV error)

My code for when a color is chosen is as so:

 using UnityEngine;
 using System.Collections;
 
 public class SelectBlackPelt : MonoBehaviour
 {
     public Material PeltMat;
     public GameObject PeltObject1;
     public GameObject PeltObject2;
     public GameObject PeltObject3;
     public GameObject PeltObject4;
     public GameObject PeltObject5;
     public GameObject PeltObject6;
     public GameObject PeltObject7;
     public GameObject PeltObject8;
     public GameObject PeltObject9;
     public Transform Slot5;
     Vector3 Slot5Position = new Vector3(4.6664f, -2.537599f, 6.239999f);
 
     void OnMouseDown()
     {
         PeltObject1.GetComponent<Renderer>().material = PeltMat;
         PeltObject2.GetComponent<Renderer>().material = PeltMat;
         PeltObject3.GetComponent<Renderer>().material = PeltMat;
         PeltObject4.GetComponent<Renderer>().material = PeltMat;
         PeltObject5.GetComponent<Renderer>().material = PeltMat;
         PeltObject6.GetComponent<Renderer>().material = PeltMat;
         PeltObject7.GetComponent<Renderer>().material = PeltMat;
         PeltObject8.GetComponent<Renderer>().material = PeltMat;
         PeltObject9.GetComponent<Renderer>().material = PeltMat;
         Slot5.transform.position = Slot5Position;
     }
 }

PeltObject5 and PeltObject6 are the ones in question, the ones that never change from their default material.
