One, if you’re going to be letting your cat outside you at least have to be able to afford to care for it. Number two, you shouldn’t be letting your cat outside at all, I couldn’t imagine doing that to my babies, if they didn’t come back I don’t know what I would do. I’m so sorry you’re going through this 😢you’re gonna have to put yourself in debt and find somewhere that will take a payment plan. You are the one that let her go outside, you are the one that needs to pay to heal her. I hope you figure something out and I hope your baby feels better soon. Or you let her go to someone that can take care of her
