YumYum has a very loud purrrr for her age. She is only one year old. She will purr when we are in our bedroom and she wants to join us which she knows she isn't allowed. She also purs when she wants canned food in the mornings. She will pur all morning long till I give it to her.
Dutchess purs when she wants out at 4am in the morning.
