Cats purr at the same frequency as an idling diesel engine, about 26 cycles per second.That's right, who needs cats when we've got diesel engines?
I've also heard people say that we can learn things from cats.
Neutering a male cat will, in almost all cases, stop him from spraying (territorial marking), fighting with other males (at least over females), as well as lengthen his life and improve its quality.Shit.
