According to Russia Today:
A cat in the eastern village of Georgia has given birth to a puppy, Georgian media reported Friday. The owner said the cat was in labor for several days before bearing a pup that has its mom’s ears and tail.

The story, which showed the cat breastfeeding her healthy pup, received substantial coverage on Georgian television. Yet zoologists have been unable to provide a definite explanation for the incident or disprove it. They have, however, suggested that radiation could be a possible cause.
