Prey has been discussed many times. If/When Kov comes back he/she MIGHT add prey animals. But killing lag is pretty much impossible. Every one has different things added to their FH Folder. It is usually the items that cause people lag. Like the saying, you can't make everyone happy. You can make presets, which, depending on how much detail you want, doesn't take TOO long. The longest time to make a preset I must say can take about 1 hour. Now making pets? That would be pretty hard. Meshes, Textures, Sizes? That would take a long time to perfect.
