Jackrabbit is nothing like seal...

Most seal I see is on the hide, not loose, so I am thinking not all of it is stuff picked up off a beach...

Angora is close, but does not have near the "spring" of good seal.

Marine Mammal Protection Act of 1972 is what hosed us here in the US. If you can find seal or polar bear from prior it is 100% legal. Post '72, not so much...
