Kevin has won the hearts of netizens and Instagram users, and this is because of his distinctive features that make him look permanently surprised.

People might think Kevin is just too cute to handle, but the four-year-old Russian Blue cat is actually suffering from hydrocephalus, which is an accumulation of excess fluid in the brain. The condition has also made Kevin partially blind and deaf.

As a result, Kevin has an enlarged face and a startled expression.

Kevin and his human companion Tailah, a veterinary nurse, first met when Kevin was around four weeks old. A lady found little Kevin in a car park and decided to surrender him to the nearby veterinary clinic where Tailah was working.

 Little angel pie! ❤️

"I fell in love with him straight away and knew I had to give him a chance," Tailah told LoveMeow. "I was warned that he wouldn't live to see six months (if he was lucky) and to not become attached. I told myself that even if he passes away, I gave him all the loving I could," she added.

But Kevin remarkably survived past the six-month prognosis and just celebrated his fourth birthday. He's never had a seizure despite having hydrocephalus and shows no signs of nausea. Although he may be a bit small for his ages, Kevin seems to be extremely happy and contented with his life.
