Are there any animals that are an in between of a cat and a dog?

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.

Okay, explain.

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.

In order to answer that, you’d need to start with a definition of what you mean by “cat”, and also “dog”.
