Kittens that little are so precious... I had a cat who had three litters... the first was by these two cats we already had when we got her, then the next was by her son (we had to wait till we could afford to take them) and the third was by her same son... but we didn't even know about it and it most have happened the night before we took Tommy and Kronk (litter number 2) to get fixed... we had to take her to anti cruelty though, cause we had to down size animals... she went to a good home though!
