Why Does Grumpy Cat Look So Grumpy?
Have you ever wondered why Grumpy Cat has that permanently sour look, despite incredible internet fame and adoration? We reveal what’s behind that permanent frown.
Grumpy Cat’s real name is Tardar Sauce and the cause of that unusual expression is actually due to feline dwarfism and a serious underbite.
Feline dwarfism is a genetic growth defect. Affected cats don’t grow to normal size and often have a characteristic undershot jaw, comparatively large head, with short limbs and bowed joints. As you can see in this picture from when she received her Lifetime Achievement Award, she is pretty small.
The disorder is autosomal dominant, which means that only one parent needs the gene to pass it onto their offspring. Grumpy Cat also has a brother with the same condition.
The truth is, Grumpy Cat isn’t really grumpy, in fact she is a pretty happy cat. She takes the frequent media appearances and international travel in her stride and hasn’t let all this extra attention go to her head.
