Penetrative sex with cats is obviously out of the question. For females, it's immoral, as they're too small to take a human without suffering grievous injuries, and for males, it's impractical, as they're too small to penetrate a human effectively, but I don't see why non-penetrative sex (e.g. oral/handjobs) would be out of the question, as they have the same intelligence and ability to consent as dogs. However, a cursory search of the forums here turned up no information on this. Could anyone enlighten me?
