Tilly has such a loud purr! She woke me up SEVERAL times last night because she was purring in my face! She is also such a tiny cat that I don't expect such loud noises out of her!

Bassett has a very soft purr, and she is HUGE! If Bassett wants to wake me up she can just walk on me

What kind of purrs do your cats have, and when do they use them?
