Grumpy Cat, the million-dollar pet who became famous on the internet by virtue of her unusually ill-tempered facial expression has died aged only seven years old.
The cat’s real name is Tardar Sauce, and her permanent scowl is a result of her having been born with dwarfism and an underbite.
But the cause of the cat’s death was complications from a urinary tract infection (UTI). In cats, urinary tract diseases can have multiple causes, including infections, inflammation, diet and behavioral issues, according to Cornell University. Urinary tract diseases in cats aren’t uncommon, and surveys have suggested they are the No.1 reason cats are brought to the vet, according to Cornell.
