It's cat-dog in real life! Maybe you should show him the cartoon, then he will understand it's a dead and impossible concept.

But that might encourage him...

I agree #13. That was one of the best cartoons of my childhood!

a baby was born, and it caused a little stir....

@13. even if it encouraged him its impossible...

no blue bug no three eyed frog just a feline canine little catdog

Catdog. Catdog!

FML, I love you guys. You make my day.

A man can dream...

Is really only just a dream /:]

I fear for your cat and dog. Good luck with him OP.

This is a man who really needs a hobby.

If the millions and millions of cats and dogs that have lived together have not been able to mate successfully so far, he isn't going to be the first to get his to do it.

Dogs and cats living together....mass hysteria!!! As for you, OP, maybe you should get one or both of them spayed/neutered so it will be impossible for them to mate with their own species.

Actually they can copulate. Small dog big cat. I've seen it. Poor kitty didn't know what she was in for, screamed bloody murder. No kippies but they tied for half an hour. Look at YouTube, there is a video of cat/dog tied together.

Is high school biology a class that he took? Or, y'know, Common Sense 101?

He's barking up the wrong tree.

So my favorite show as a kid, Catdog, is fictional? Thanks. Childhood = Ruined

Dogs also dream about getting some pussy.
