"If there's one message I'm getting out, it's if you see a seal on the beach, let him be. Often mom is coming back. And call the seal rescue group in your area so we can check it out."
Onion Flake, on the other hand, wasn't an orphan. Just really, really unlucky.
"He was what's called a weanling when rescued," Zagzebski explains. "He had probably been on his own for two or three months by that time and he just got sick."
"There are two really vulnerable times for seals," she says. "One is that first month when mom is leaving them on the beach.
"The second is right after they've been weaned and on their own for a couple of months - they're still young animals, they're still really fragile and they're subject to a lot of illnesses."
In Onion Flake's case, he caught just about every one of them.
