I've never heard my cats snore, but Tilly tends to let out a really long, contented sigh when she is just falling asleep! AWW!

My parents cat, who is terribly overweight even though they have tried all kinds of weight loss stuff, snores really loud.. its really funny!

As for my house, I would have to say that I'm the noisy sleeper.. I snore, and I'm not ashamed to say so! Mostly because I couldn't hide it if I tried!!
