Cat gives birth to DOGS?! What?

Apparently a young woman and her husband are claiming their cat Mimi gave birth to three kittens (all of which died) and three puppies. This really is an odd sort of a story, and the details are scant. I have no idea if they witnessed the birth or not, but it seems like it's a hoax. Oftentimes animals will adopt babies (or even adults- there was a case of a lion that befriended a chicken at a zoo) of other species and raise them as their own, especially if they lose their own natural offspring. The puppies in the photos (http://news.yahoo.com/photos/ss/events/sc/111606catbirthdogs/im:/061117/ids_photos_wl/r3413684871.jpg) look like exactly that- puppies. There doesn't appear to be anything cat-like about them suggesting hybridization. Furthermore, cats and dogs have widely different genomes, varying even in the number of chromasomes (dogs have nearly double the # of chromasomes as cats) which essentially assures that viable offspring would not be produced from a mating between the species. Sure, they both belong to the Order Carnivora and most likely shared a common ancestor similar to a weasel at some point in their past, but it's not like you're hybridizing a lion and tiger (which has been done).

According to the news, a scientist is testing blood samples from the puppies, and I suspect they'll show up to be just that. I don't think this is much more than a hoax or misunderstanding on the part of the cats owners, but if a cat really did give birth to true dogs (not hybrids) it would fly in the face of everything we've come to understand about sexual reproduction and speciation. Still, I don't think geneticists have much to worry about here, and there will likely be a perfectly sound explanation for this.
