What fencing  did you  use? If it is chickenwire, Raccoons, dogs can tear right  thru it.
		
		
	
	
		
	 (they have all night). If you really want it  predator  proof, add hotwire, 6" offset on bottom(with stakes, you can drill a hole in plastic water pipe or buy the ones for  dogs.) or offset electric fence connectors .And may want to add one further up.....Just trying to  prevent  tragedy.....
