Okay, technically a hedgehog is a rodent, not a pig, but they are called hedgehogs, and they are extremely cute, and my collection does contain a few of these token members of the porker family..
This is my most interesting one. It's a cast iron hedgehog doorstop that once had a brass finish, but it's worn off- can't remember where I picked this up, but it was long ago...at least 5-10 years, anyway..
Just to show you that it is in fact a working doorstop, I've put up two views of the wee beastie..in case you were suspicious about it's utility, and thought it purely ornamental...
