Dangerous Unconventional Pets

Even though he's surrounded by danger, MacInnes has so far escaped unscathed.

"We've never had a serious -- I want to knock on wood -- we've never had a serious envenomation here. We've had, you know, close calls where someone gets a fang but doesn't get any venom. But mostly it's because we train, stay real safe, stay at the other end of the hook or the tools," he said.

Yet just a day after ABC News visited MacInnes' farm, a neighbor who had bought snakes there was bitten by his pet cobra and had to be rushed to an Orlando hospital for emergency treatment. He survived, but buyer beware.

Pythons are not native to the United States, yet somehow they have escaped captivity in their new homes and made themselves comfortable in the Florida Everglades, where they have had run-ins with cars, alligators and cats.

It raises he question, if these nonindigenous animals are escaping into the wild, is it really appropriate to sell them in the United States?

"I think so," MacInnes said. "I mean, we've been selling snakes, you know, for 50 years in Florida and this is one of the very few species that has ever become established, and it was basically a freak thing that happened. And it's probably because of Hurricane Andrew and one or two snakes -- it's yet to be determined how many snakes -- but a few snakes have made their way to the everglades and started breeding."

Frogs and Scorpions and Spiders, Oh My!

Away from the giant snakes, a collection of colorful red-eyed tree frogs selling for $45 each, seems awfully appealing.

There also are white tree frogs, African bullfrogs, blue frogs and huge toads. But don't let colors seduce you: These guys are poisonous, although not when bred in captivity.

Some people get a kick out of owning scorpions. These creepy crawlies are $5 and up. But if you're thinking of buying a tarantula, don't plan to touch it -- its hairs hurt.

"They kind of just float in the air. They get into your nasal passages and your eyes and your skin and make you itch, and it keeps predators away from them," MacInnes explained.
