American Airlines reportedly announced new guidelines that restrict what passengers can pass off as emotional support animal.

Sorry, hedgehogs and goats…you’re out.

The new rules take effect on July 1. The Chicago Tribune reported that passengers will have to submit documentation 48 hours before their scheduled departure and a mental health professional must sign off.

The list of animals banned include amphibians, goats, hedgehogs, insects, nonhousehold birds and animals with tusks, horns or hooves, according to the paper.

Passengers with trained service animals will not be impact by the protocol changes. Miniature horses trained to be service animals will still be allowed to fly, the paper reported.

American spokesman Ross Feinstein told the paper the airline sought feedback from disability advocate groups before announcing the new measures.

United and Delta Air Lines announced similar policy changes earlier this year, which tightened their regulations on emotion support animals by requiring passengers to provide special documentation for service animals trying to board a flight.

While federal regulation requires airlines to permit service animals to accompany passengers with disabilities in their seat, there has been a growing number of concern about the type of animals passengers have been bringing on board – including comfort turkeys and gliding possums.

Sen. Richard Burr (R-N.C.) introduced new legislation in April to correlate the definition of a “service animal” under the Air Carriers Access Act with that of the Americans with Disabilities Act.

The move would create criminal penalties for those misrepresenting their animal as a trained service animal, in addition to requiring federal agencies to lay out behavioral guidelines for service animals working on an aircraft.

Rep. Bill Shuster (R-Pa.) is proposing an amendment calling on the U.S. Transportation Department to clarify existing policies.
