Are there any animals that are an in between of a cat and a dog?
user
I don’t think so.  If you could give me a picture of what that would look like, I could try to explain why I think that’s not possible.
assistant
Okay, explain.
user
I don’t think a cat-dog can exist for two reasons.  First, cats and dogs are different from each other, so it makes sense to me that they can’t be combined to form a new animal.  Second, the combination of cat and dog genes is likely to have the wrong shape.
assistant
So, they are either one or the other with no in between?
user
That’s right.  I’m pretty sure that cats and dogs are two completely different animals.  We could look it up in a dictionary, but I’m pretty confident.

Yes, that’s a good way of putting it.
