As marie mentioned, Dr Elseys brand does make a Kitten Attract litter. I found it best to sprinkle a little bit on top of whatever litter I wanted my kitten to use (it tended to be sticky on the paws if I used too much). Of my 4 kittens all were trained before 12 weeks, except Simba who would pee right beside the boxes. We put tarps under/around each box (still works well for litter tracking). What he did like was a small box with puppy pee pad in it; we called it his urinal. He used it until he was about 20 weeks. Komet, our newest kitten, was completely trained by 10 weeks and is a male as well.
Your little guy may not like the litter. Most of ours came from catteries using pine pellets, yet they hated those. We switched to walnut litter non clumping to begin and they all love that. You may have to experiment to find what your kitty likes.
