Sorry folks. Seems like the cat and dog in Brazil didn't really have kuppies or pittens. They're just cats that look a lot like dogs. I really did find this quote to be in bad taste, though:

"People who aren't experts often imagine things," said Pacheco, director of the Institute of Biological Sciences of the University of Passo Fundo.

Wow. I nominate him for most pompous scientist of the year.

Edit: OK, I must admit, after reading the little article again, I think they're saying that the cat adopted the puppies as her own, so they're not kittens, they're puppies, which are being nursed by a cat. Confused yet?
