Comparing our two:

Carrie is very vocal indeed, and it's a proper meow.

Jasper, by contrast, squeaks. We got him at around the same time as our
then next door neighbours got themselves a puppy. One night, we heard
Jasper squeaking to come in, but the noise was so un-cat-like, we
thought it was Benson whining.

The only time Jasper makes "proper" cat noises is when he's discussing
boundaries with the cat next door!
