Ok, so I have a quick question. My kitties will be 6 weeks old this Saturday. Is that to young to litter train them? How do I go about doing that? I bought a litter box(that they could climb in and out of with ease) today, and I was just wondering...Also, I have three, so will they use the same one since they are so young...or are they like adult cats and need their own? Sorry for all the questions...but thanks in advance!
