I have that same feelong when I go by an adoption center, and these Little Faces are staring at you with such longing in thier eyes.

And you can tell the ones who have been there a while as they just lie there sad, while the New Arrivals try and get your attention.
Hey look me over Mister , Im a Good Cat REALLY!!!

Psst over here , over here.
And you leave and they sit down, and soon they dont bother to get up.
Its the so called Guardians who should be in cages , not The Poor Animals.
