You better believe I understand what they say and mean sometimes! I know those looks and what they mean too. If I don't act on them soon, I am a goner! They'll take care of me fast. So, I make sure I do their bidding as soon as possible.
They let me know when they are hungry, or want their bed changed, when they want petting and when they want to play, and when they want love, if I am too slow to give it to them first. They also let me know when they hear things or people outside or something is bothering them. They are hard task maskers sometimes, but also loving companions always.
