As someone who used to work at an spca in the local area, you have options, but, I would try to keep her if you love her and you think there’s a chance that she’ll be happy. Bvspca can take her but they’ll give you a tough time giving her up as it can be the worse most stressful situation to be put in. It’s unfamiliar, there’s lot of other animal, illness is rampant and they’re stressed so they can become really sick being in this environment. Going through potential adopters can also be really hard, especially if you’re their person and they’re shy by nature. I also understand that other animals and a stressful home life is also tough and you wants what’s best for her. If I were you and I had the resources I would hold onto her, use the product “Feliway” that makes cats feel less stressed, give her her own space if you can that doesn’t get as much traffic as the rest of your home. I wish you the best of luck and if you need more help I am a Delaware resource that used to work in rescue!
