Kellie, you used Color Catchers which was good. I've used Kona black cotton before, and it does bleed. Many black fabrics seem to bleed. Prewashing helps...I use hot water on black to release the extra dye and also to get the maximum shrinking done. Sometimes the process needs to be repeated and I do that until the Color Catchers come out looking like when they went in (white). Some colors fade and so prewashing them lets you know that and whether you want to use them or not.
