With his beautiful grey fur and huge eyes, Simba has quite the following online.
The adorable cat is often seen relaxing in odd places and looking surprised.
And while grumpy may not be his go-to reaction, he can look pretty convincing when necessary.
"I need a new human"
A recent clip, which shows Simba lying on his back in his owner's arms, has now been viewed 1.4 million times.
In it, his owner moves his face, which immediately makes him look like the grumpiest cat around.
"I got a free face massage but the guy kept making weird sounds while he was doing it", joked a viewer, as he imagined what the cat might be thinking in the moment.
Divided opinion
While many cat lovers found the clip amusing, others questioned how comfortable Simba was with the interaction.
"Insta people use animals as toys. Not funny", wrote one outraged viewer.
"If I do something my cat doesn't like, he'll bite and try to scratch me", explained another, suggesting that if the cat were unhappy, he would have made his feelings very clear.
