Yes, Dog litter. No, it is not like cat litter. It is much bigger granules and it is not at all like cat litter. I bought it at Pet smart about $8.95 for a bag. I tried it and the first day Stormy used it and I was so excited! You can google it and see the testimonials on it and how it works- that is what I did. My puppy is baout 17 weeks and we are completely potty trained. If you are in cold weather it works perfect!
