The Furry Friend Cat Purr Generator is an online sound generator that sounds like a cat's purr. That way you can enjoy the relaxing sound of a good purr when you're out of town and missing your own little shit nugget back home. You can adjust all the sliders from sub-bass to high treble to really fine tune the purr to just the way you like it. Alternatively, record your own cat's purr and play that. Don't have a cat? Record your dog barking. That's relaxing, right? I like to fall asleep to the sound of construction and police sirens.
Thanks to Lydia, who agrees there needs to be an online cat kneading generator.
