Me and my daddy are both INTJ's and neither of us are very warm hearted to people in general, but very affectionate to our loved ones (though there may be few.) My dad has a soft spot for animals and babies as well.
I however, am not very fond of babies and animals. (but I love baby kitties.)
And we both happen to be extremely funny. My jokes tend to have a pessimistic nature, and my dads are usually just perverted.
