Paris Hilton scrapped her ambition to become a veterinarian when she discovered she would have to kill animals as well as save them. The hotel heiress loves animals and dreamed of working with them when she grew up - until she found out the job has a gruesome side. Hilton says, "I first wanted to be a veterinarian. And then I realised you had to give them shots to put them to sleep, so I decided I'd just buy a bunch of animals and have them in my house instead."
