Ah she is really much too young to be able to tell... but as she gets older certain traits may come out and you'll be certain!

If you just have two cats your adopted from the shelter, or two strays that were runnign around; basically two cats whos' origins you don't know and aren't a registered breed they are generally referred to as "Domestic Short/Long Haired". DSH (Domestic Short Haired) being the most common.

However as I said, as she gets older and reaches maturity if she has more distinctive breed traits in her they will come out. But now it seems its just too young to tell.

What a SWEETHEART though!!!
