Frontier Airlines offers free flight vouchers to people who adopt kittens

Frontier Airlines has said it will give flight vouchers to anyone who adopts one of three kittens from an animal shelter in Las Vegas - each of which is named after an airline.

The two-week old kittens - named Frontier, Spirit and Delta - are at The Animal Foundation, Nevada's largest animal shelter, and will be up for adoption in around a month once they are larger in size.

After learning about the names of the kittens, Frontier announced that whoever adopted Spirit or Delta would receive two $250 Frontier vouchers, while the new parents to Frontier, the cat, would get four $250 vouchers.

Frontier tweeted that it was honored to have given its name to a kitten and offered the vouchers in exchange

It all began when The Animal Foundation, which has a habit of giving its cats and dogs quirky names, posted the pictures and names for the trio of cats.

It even joked that one of the kittens was going to be called Southwest, but due to struggles the the airline faced over the holiday season, the name was canned.

'Meet the newest additions to our kitten nursery! Spirit's name used to be Southwest, but due to recent events, our marketing team requested we change it,' it wrote on Twitter.

'This is so sweet! Thank you for the honor, @animalfndlv! We'd love to donate two flight vouchers each to the people who adopt @Delta and @Spirit and four vouchers to the person who adopts Frontier,' the airline's official paged tweeted in response.

In a statement explaining its decision to gift the vouchers, Frontier said the shelter's cause was aligned with its values.

'We were delighted the rescue organization decided to name these three adorable kitties after airlines, including ours,' Frontier said. 'Underscoring the plight of animals is near and dear to us.'

'We were more than happy to provide a little extra incentive to encourage the adoption of these three precious kittens,' Frontier added.

The Foundation said the three kittens were rescued from within Las Vegas at the end of last month. They will be available for adoption when they weigh 1.5 pounds and are at least six weeks old.

'It's unusual to have a litter of kittens in the shelter this time of year, so when we had these three itty bitty fluff balls arrive at The Animal Foundation, we knew we had to give them special names,' Animal Foundation spokesperson Kelsey Pizz told CNN.
