Tortoisesupply.com sells them. I bought some from Amazon. I planted a few pads that I had bought in flower pots now I don't have to buy them anymore. Plus now I get the fruit that the prickley pear cactus produce. They love that as well. I live in the Pacific Northwest. The cactus grows just fine outside here. I'm not sure where you live. It might be much easier for you to find if you live in the southern states that border with Mexico.Where do I get cactus pads??
