As the title states, my cat got out last night and I didn't find out until a couple hours later. I found her stuck behind a fence outside. She was growling and hissing at me, I have never seen her act like this before. Eventually I caught her and took her back inside, but now she keeps growling/hissing at me. She did come up to me for pets once but immediately started growling again. Any advice? I gave her some wet food and am giving her space right now.
