I have this thought often, too. The way I see it, some biologist probably already concluded this can't or won't happen. If it was a possibility, we would already have Cat-Dogs!

You don't need to be a biologist to be able to 'conclude' that they can't...

#18 Ha-ha! This comment proves that OP's husband is not stupid: he's just ignorant, because he didn't read the scientists' paper on catdogs. But, #18 did read it, and... Bummer... You can't cross-breed cats and dogs. Lol! :)) ha,ha,ha! FML: will always lower the bar of stupidity :))

Well hey now, everyone thought animals from different genera couldn't cross breed, but goats and sheep proved us wrong. Everyone though mules were sterile, but a couple have had babies! Weird things happen sometimes. It's highly unlikely cats and dogs will ever be able to breed together (naturally anyways,) but technically there's always that teeny tiny chance.

They can. Just no offspring. Dogs will f&#$ anything.

I hear that works on elephants and pigs too...

Sorry 47, but haven't you heard that song from Loverboy?

Pig and elephant DNA just won't spliiice! Says nothing about cats and dogs though, so give your husband a chance, OP!

smh #20...

#20, thanks for taking one for the team!

If the person trying to breed the animals was someone educated (veterinarian, scientist, etc.) then it wouldn't be animal abuse. If they mistreated the animals during the process, yes.. but just breeding animals isn't what is harmful.

It doesn't matter who is doing the breeding--inter species breeding is generally frowned upon. It was once common for scientists to experiment with cross breeding similar species, such as lions and tigers, to create new hybrid species, like the liger. Today, many in the scientific community look upon that time with disapproval. Experimentation is one thing, but to mess with actual living things, especially to produce results that would never occur naturally, for no purpose other than amusement is unethical.

#38 Ha, ha, ha! There's no escaping you! You're spamming the comments with "educated" opinions. Ok, it seems like we, as an FML community, have no choice but to give you some insights in order to improve the quality of your comments. First off, breeding between 2 different races it's impossible in nature. For various reasons. If you want more details, look it up yourself. Second, because a cat and dog can't breed naturally (see above), by trying to breed them in a laboratory, would be forceful and unnatural, and as such, labeled as "animal cruelty". P.S. Go read a book from time to time.

Races? I think you mean species, dude. If you're going to criticize someone, at least make sure you've got your own facts and terminology straight.

To continue on #94's comment to 90... It wouldn't be animal cruelty in a laboratory. They would t waste time trying to get a dog to **** a cat they'd just artificially inseminate the cat with the dogs sperm. If that's animal cruelty we should probably call the U.N. about all those humans being treated cruelly when they get artificially inseminated.

Your comment reminds me of the movie Splice. That was a messed up movie.

Yea it was very messed up. I will never watch it again.

The genetic make up of cats and dogs is completely different, that's like asking why you can't have children with a goat.

it is impossible, I think you need to confront your teacher if s/he is telling you it's possible to cross breed animals such as cats and dogs, or maybe pay more attention, tigers and lions can cross breed, maybe that's what your teachers was saying, doesn't mean cats and dogs can

#31- it's possible to have a baby with a goat, don't you read Cyanide and Happiness? XD (For all those pathetic ***** out there that think I'm an idiot, just search "Cyanide and Happiness goat marriage" on Google images. First result.)

#22 Animals such as lions and tigers can breed because they are very closely related (but won't produce fertile offspring).. dogs and cats cannot breed because they are too genetically different.

The female Liger (male lion + female tiger) can be fertile and have offspring with either tigers or lions.

A lot people also say mules (horse x donkey) are infertile (that's what I'd always thought, too), but I read somewhere that they aren't always... I'll have to look that up again.
