So... I've started to hope that i might be able to put Runty & Stubbs up for adoption. They've started showing some signs of improvement.. Well, Runty's not as vicious and scary as she used to be and Stubbs has started communicating with me. She's also showing signs of wanting to socialize with the other cats in the house. The other day, when i opened their cage to feed them, Stubbs even slipped out of the cage and brushed up against my arm before exploring. Runty of course, remained curled up in a tense ball of fear but at least she didn't hiss at me to the point of spitting.
At the very least, it might be possible for Stubbs to be socialized enough to be adopted? Maybe we'll find someone kind and loving enough to like Stubbs and also be willing to adopt her feral sister? I really don't wanna just spay and release them. That is absolutely the last resort.
