Aly,

IMHO, you did the right thing. She is at peace now at the Bridge, no longer suffering. Please don't feel bad or guilty. If you hadn't come to their rescue, she definitely would've died from neglect. I commend. I hope the kitty will find a home. I also hope the owners rot in hell for what they did. They should be brought up on charges. You have every right to feel angry at those who treated those poor animals the way they did. Bless your heart.
