Cats do not belong in cages. Cats deserve to be free. SMASH THE CAGE! No cats in the cage.
If someone taps you on the shoulder in the dark, I can't imagine it matters who they are, you're going to go into immediate fight-or-flight mode. That shit is scary.
I wouldn't adopt a squirrel. Red squirrels are endangered, and Grey squirrels are the reason the reds are endangered... so I'd kill a grey squirrel on the spot if I could, and set a red squirrel free.
And I wouldn't take home flowers. What the hell would I even want with flowers? Taking them home is killing them. Let them live. Leave them be.
