My cat was neutered about a month ago before he was ever let out so hopefully he'll never become a rapist.
His neutering, typically, went a bit wrong somehow though... some guts from inside his ballsack prolapsed out of the hole in the scrotum after a few days, and then it just healed like that... so it's now fine but he will forever have a deformed, testicle-less scrotum
.
Also, I now call him "Reek". Seriously. Haaa...
