I really like the cigar sometimes is just a cigar interpretation of this dream in this case: you are a cat person dreaming of cats, maybe they represent ... cats? Unless you have a strong sense that they are not what they appear to be. If the cats are just cats, this dream could have happened as follows: in your dream you noticed bad weather snow outside, so you think "I hope none of my cats are out there". Boom! That thought causes a cat to be out there. You rescue cat, but notice that something is not right, that your dream cat is not like you real life cats. What's off? It's white. So you think: ah, but neither of my cats are white, so this is a third cat. Boom! That thought causes all three cats to appear.

It could be as simple as that with no hidden meanings. Unless the dreamer has a strong feeling that there is a hidden meaning, there really does not have to be, when a cat person dreams of cats.
