Do Cats Cry When They Are Sad Or Hurt?

They may not cry tears as we humans do but they do experience loss of lifelong mates including humans that die or have to give the animal up. They know pain and suffering as well and show signs of it as well. They can become depressed and lonely at the loss of a kitten(s). My wife and I have seen this in several instances over the past 25+ yrs. But I have not sen one "cry" as tear type crying but they do have a different "meow" consistent with depression etc. Not all cats apply to this rule however. Generally domesticated ones....not feral or wild cats of which we also have several of but had not noticed this behavior.
