Las Vegas Animal Foundation was delighted to learn that Frontier Airlines is offering free travel vouchers to anyone who adopts one of three newborn kittens the hospital just received.

The three kittens are just two weeks old, and their eyes aren't fully open yet. They were found in the north of Las Vegas and were given the names Spirit, Delta, and Frontier, for unknown reasons.

Per pet parent, Frontier Airlines, who got word their name was being given to a tiny kitten, is offering two $250 vouchers totaling $500, which are redeemable until the end of the year. For those looking to adopt Frontier, Frontier Airlines is doubling that.

"We were delighted the rescue organization decided to name these three adorable kitties after airlines, including ours," said Frontier in a statement emailed to CNN. "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."

The foundation said it's rare to get a litter of kitties in December. At the moment they are living in a foster home until they are 6-weeks old or 1.5 pounds in weight, at which time they will be available for adoption.

It's been one of the worst years for passenger aviation in history, but not always for four-legged, finned, or fluffy passengers.

WS reported back in September that when a passenger's beta fish was denied boarding in Orlando, two Southwest Airlines employees offered to take care of it for 4 months until the guest came back to Florida.

Also in December, United Airlines employees applied by the dozen to adopt a black shepherd dog abandoned at SFO.

"Sometimes we deal with the craziest of situations," United Director of Customer Service Vincent Passafiume said at the time. "This was probably one of the oddest we've ever dealt with and also one of the most challenging."

"To be able to get the outcome that we did as a team and see that Polaris will go home to a family that will give him a good life is really a special moment for me."
