Just as the title says, I can't hear my cat purr. Or rather, his purr is too quiet to hear. The only way I know he actually does purr is by putting my ear to his neck/shoulder area to hear the very quiet rumblings of his purring. He has no issue communicating through meows and chirps, he is quite vocal in that respect. He was rescued as a stray at about six months old by the RSPCA. We've had him for over two years now and he is a very happy cat. But the purring issue is still puzzling to me. Is it unusual? My previous cat had such a loud purr, and he would purr for extended periods of time as well.
