Gandalf, my boyfriend's fluffy blue-grey, long-hair kitty doesn't really ever meow. He looks just like his sister Bella who has black hair, and also lives with another of his sisters named Biscuit who doesn't look like either of them with short, dilute tortie hair.
Mainly, he'll meow when he's impatient for food, tiny meows that just seek to urge me along. And while Bella isn't as silent, she'll meow and make noises when she plays. She'll also begin to purr immediately and healthily when I pet her. Gandalf rarely purrs, and when he does, it's low and also quiet. He usually only purrs with my boyfriend (I think he prefers males).
Biscuit, on the other hand, is very vocal! She'll tell me whenever she needs something: food, water, cleaner litter, play time, more food, more food, MORE FOOD! Mew mew mew! lol If it weren't for her, I wouldn't know until much later when anyone needed anything. She has been my Kitty Needs alarm.
Do any of you live with very quiet kitties?
