An older cat with medical issues found himself at a shelter after his beloved owner sadly passed away—but with the help of rescue workers and his foster parents, he began to flourish.

Tuxedo cat Zorro has become an online sensation after his former shelter, Cat Town, shared a video of him being the perfect patient while being treated for asthma.

Cat Town specializes in helping cats who "might struggle to get adopted from a shelter cage," staff member Quinn White told Newsweek. And eight-year-old Zorro, who has feline immunodeficiency virus (FIV), dental issues, calicivirus and asthma, fell into this category.

Despite these issues, White described Zorro as an "absolute dreamboat" who "flops down on the floor right by your feet and looks up expectantly when he wants you to pet him."

Now a clip shared to Cat Town's TikTok account, @cattownoak, has seen hundreds of thousands of people fall in love with Zorro, as he patiently took his asthma inhaler.

Posted on September 26 and already boasting more than one million likes, the clip shows Zorro sitting on the floor looking up at his fosterer, who brings a small hand-held inhaler to his face.

Without a second thought, Zorro places his face inside the mask, and sits perfectly still as his foster parent slowly counts to five. When it's all done, he's immediately given some treats, and, knowing the drill, Zorro rushes straight to his bowl.

Praising his foster carers for going "so above and beyond" for Zorro, White explained the rescue sent medication and information on training a cat to use an inhaler when these fosterers first took Zorro into their care.

"His love for treats really helped with this, and it only took him about two weeks to learn the routine: they started with a treat in a bowl, using smaller and smaller bowls until he graduated to the face mask," she explained.

"Zorro now gets two puffs in the morning and two puffs at night from his inhaler, and the process takes about 10 minutes each time, from getting him geared up and ready to enjoying his treats!"

Zorro's foster owners proved the perfect carers for him in more ways than one, as after getting to know the cat and perfecting his routine, they decided to adopt him.

"It really felt like a perfect fit to us," White said. "They just love the little guy to bits!"

They aren't the only ones, as TikTok users fell head-over-heels for the perfect patient. His video has been viewed over 7 million times and received thousands of comments, with one user calling him "such a good boy".

"This is incredible," one wrote. "This would be great to show to little kids who have asthma and other respiratory issues."

One pointed out "the eye contact" from Zorro to his owners, as one declared "Tuxedo cats are in another level when it comes to being smart."

"Awww he put his little snoot right in the inhaler! I love him," another said.

Cat Town was overjoyed by the enormous reaction to Zorro's video, with Quinn telling Newsweek: "We've seen comments saying that he can help inspire children with asthma, that he's helping people whose cats have asthma learn they can make the whole process less stressful, and of course folks recognize that he's absolutely precious.

"Hopefully people who see Zorro will think about adopting a cat with medical needs, because he's done such a good job of showing that it can be a joyful part of the relationship you can build with a cat."

Cat Town, based in Oakland, California, has been operating since 2011, and thanks to its work focusing on older, injured or sick cats, have "helped reduce the euthanasia rate for Oakland's shelter cats by more than 70 percent," White told Newsweek.

Each year across the U.S., around 920,000 shelter animals are euthanized, including 530,000 cats, according to data from the American Society for the Prevention of Cruelty to Animals (ASPCA).

The number has declined since 2011, where approximately 7.2 million animals were euthanized.

In 2014, Cat Town opened the first-ever Cat Café in America, letting people enjoy a meal with the animals while also teaching their rescues to become socialized with humans.

The cat café will be celebrating its 10-year anniversary this later this month.
