The project idea is not mine, I just created another version of the project. The orignal can be found at http://scratch.mit.edu/projects/FIDELCASBRO/1590239 Drag your mouse over the project to see the hearts. If you let it play for a while, the cat's movement start to move out of sync, I don't know why though. Please let me know if you have any suggestions. From the original project, I had made the cats move and instead of the heart bounding around, I made it into a stamp that followed the mouse.
