We should really consider the facts of the incident. Commander Drewcarnegie stated categorically that he is the father of two (2) cats, so we can only surmise that the cats are twins, because to repeat this mystifying feat more than once borders on the suicidal. Next fact is that the good Commander is in fact a male of the species, since he stated he is the father of said felines. Since he is lacking the necessary plumbing the only form of birth that could occur is a caesarean birth and one could safely assume an anaesthetic such as an epidural would have been administered. So no matter what dangly bit the kitten(s) saw immediately after birth, no pain would have been felt by the good Commander.
Of course, once the epidural wore off, I do imagine tears would have flowed freely .....
