My cat has a few type of meows.
  • the regular meow
  • the purr meow combination (sounds like a pigeon cooing)
  • and a low sad sounding meow when he thinks I'm not there.
These are the only ones that I've heard from him so far. Does anyone know what these sounds actually mean?
It seems that the regular meow is to signal for someone's attention.
The sad sounding one seems like he is unhappy.
What are some other ones that people have heard? What do they mean?
