A Brazilian women has claimed that her cat mated with a dog and has now given birth to dog/cat hybrids. The kitten genuinely to have dog-like traits.

Personally I really doubt it. If dog/cat crossbreeding was possible, it should have happened centuries and people would have already used it to breed a whole new species of domestic pet.

Still, it's interesting. I hope we get the results of the genetic tests.

There are oh so many quips to be made here. For a start, perhaps they were fighting like cats and dogs, and had make-up ...

Impossible.

Never dismiss the possibilities of one-off mutation. I'd be surprised if the hybrids themselves are fertile, though.

Cute little darlings though, even if they do take after their dad. Look how proud "mommy" is.

Dogs have 78 chromosomes, cats only 38. Drat, but as interesting as this is, it just doesn't seem possible.

Well, there are wolphins (whale/ dolphins), zorses (zebra/horses), ligers (lion/ tigers) and of course the mule. www.ratbehavior.org/Hybridization.htm

Not possible - they are totally different types of animals - felines and canines - horses and zebras, dogs and coyotes, yes, cats and dogs no.

If it were possible to mix a cat and a dog, I'm sure you'd see them all over, but there are several barriers, prezygotic (before the egg) and post-zygotic (after the egg) to whether or not an animal can reproduce with another animal. They are:

Prezygotic barriers can either cause difficulty in mating or prevent/hinder the fertilization of ova if members of different species attempt to mate. These barriers include the following:

A) Habitat isolation – this example involve the rare, chance encounter that two species may have if they live in different habitats but are not separated by geographical isolation (ex: two species of garter snake that are in the same genus live in the same area, but one species lives mainly in water while the other remains on land).

B) Behavioral isolation – Special signals or unique behaviors used to attract mates are the most important reproductive barriers among closely related animals. (ex: courtship rituals between two closely related species of birds)

C) Temporal isolation – This occurs when closely related species mate at different times of the year (ex: two species of skunks that overlap in range but one mates in late summer and the other in late winter; plants that flower on different days)

D) Mechanical isolation – anatomical incompatibility

E) Gametic isolation – zygotes cannot form after sperm and egg meet. The sperm will very rarely fuse with the egg probably because of recognition components on the egg that will only accept a certain sperm.

Postzygotic barriers occur after fusing of the egg with the sperm but barriers exist after fertilization to prevent development into a viable and fertile adult. Some examples of these types of barriers are as follows:

A) Reduced hybrid viability – genetic incompatibility

B) Reduced hybrid fertility – hybrids are usually infertile (horse and donkey mate but produce sterile mule so genes are not passed onto the next generation)

C) Hybrid breakdown – this involves reduced viability or fertility of offspring. The first generation of offspring may be fine but continued mating results in the offspring being very fragile ]...

Two species that are closely related can mate and produce offspring, Lions and Tigers are all of the family Felidae and the genus Panthera, indicating the species are closely related. Horses, Donkeys and Zebras are all of the family Equidae and the genus Equus, Dogs, Cyotes and wolves are all of the family Canidae and the genus Canis. They're all closely related species, like mating with a cousin, you can do it but you get slightly defective offspring...

When considering whether you can mate a Cat and Dog you have to look at how closely related the species are, and in this case not at all. Cats are the family Felidae and the genus Felis and Dogs are the family Canidae and the genus Canis.

I imagine she'll be sowing the body of a Monkey to the tail of a Fish and telling us it's a Mermaid in order to get her face in the papers next.

More insane ramblings by the people who brought you beeeer milkshakes!

It's depressing how well that describes my love life.

Dogs and cats living together! Mass hysteria...

Edited to add: All these years my dog has been chasing my cat...hmmm...
