Runty & Stubbs' upcoming release..

I think I will be releasing Runty and Stubbs this Thursday or Friday. They have recovered from their spay surgeries already. I don't feel good about it. I've never had to do this before. All previous fosters became tame and adoptable eventually. I know I can't control what they do once I have released them but I hope that even though they are still afraid of humans, they will know to come back to my house everyday for food. If anything happens to them while they're out there, I won't be able to forgive myself but I can't keep the terrified little kitties in my house anymore. It's too stressful for them, its been too long without any progress, and they don't want to be around people. this is one situation that i've got to let go of but its just so difficult to do so. i keep worrying that i'll find them dead in the neighborhood one day. omg why am i so bloody paranoid and neurotic.
