Out of all the kittens we've hosted here, and there have been quite a few, Ramona Clover might just have the best purr.
He motor is almost always in a state of idle. In our quiet house, you can hear it from across a couple of rooms. She purrs when she's just sitting still doing nothing. She purrs when she's being wiggly. She purrs while she eats. She'll purr if you look her way, and if you pick her up, she revs it up, and it gets three times as loud.
I know that all of our little Clovers are happy things, but because Ramona Clover has the best motor, and she expresses her happiness best.
