Thomas Cook claims to have become the first travel company to remove animal excursions from sale.
The action has been taken as a direct result of audits carried out against independent standards in line with animal welfare organisations.
“We will continue to work to raise standards at the animal-related excursions that we offer so that our customers can be confident in all of the trips that they take with us on holiday,” Cook said.
The group revealed in April that is was to stop selling tickets to some wildlife attractions to protect hundreds of dolphins, elephants and other animals from appearing as cruel entertainment for tourists.
Group chief executive Peter Fankhauser said at the time: “Our industry has not changed fast enough. By taking these attractions off sale, we are sending a message that we won’t accept anything less than full compliance with the welfare standards our customers would expect.”
