Well, I find this one "hard to swallow", too, although I believe you. Tomcats are not carers in any sense of the word, except when a tab happens to be in season, and then it's mutually-agreed rape.

Red, my red-point Siamese tom, hated kittens with a passion that bordered on the murderous. But he knew I wouldn't tolerate him knocking them about and he was a fairly easy-going cat in most respects, so we came to an arrangement whereby he didn't beat up on the kittens and I didn't beat up on him. I have a treasured photo of him lying on the couch in the lounge, with a bunch of six or seven-week old kittens mobbing him. The look in his eyes in the photo says it all: "Gemme outta here!"
