Giant Leopard Moth Caterpillar

I found this caterpillar outside our front door.  It was there for several days so I took some pictures of it last night.  I looked up information on it online since I had no idea what type of caterpillar it was and found it was a Giant Leopard Moth Caterpillar which will turn into a Giant(Great) Leopard Moth.  The name giant and great are both used to name it.

Here is a short Wikipedia article on it. Giant Leopard Moth
