Watch Out!
The majority of veterinarians have dealt with their fair share of pets that were difficult to control or aggressive. Because of this, the majority of people who left comments on the post on Reddit were curious as to what exactly this cat had done to merit having such a severe warning label affixed to his cage.
It turned out that the cat was right to be grumpy about something after all. He had undergone surgery to remove a blockage that was causing excruciating pain in his urinary system. The poster claimed that this cat is actually the friendliest of her cats; however, it appears that once he gets to the veterinarian, he becomes the complete opposite of what he was before.
