I have a question that I hope you guys can help me with. Where we live there are open fields, and we got a small field mouse in the garage. We had taken the regent out of the car to wash the cover, and did not realize that the mouse was in the garage. It chewed on part of the foam and padding around the edges of the seat and around where the bottom harness straps go through. Do I need to replace the foam and padding? My ds is above the slot where it chewed, but I did not know if it would still be safe.
