Half Feral Cat Dilemma
So I have a female lynx point siamese. She was pulled from a feral colony at around 8-9 weeks old. I also have her brother from another litter, another lynx point siamese who was pulled at 6 weeks when we finally caught the mother.
The female has always been scared of her own shadow. She camps out in one area of the house, under the sink. She has always been that way. She will not venture out of that room. Nothing like feliway or anything else has ever worked. Recently she got scared when the laundry room took on water when our washer broke, and has been sitting in a corner right behind the litter box peeing and pooping herself. I'm at a complete loss. She is a year old, and she has never been able to operate like a normal cat. Valium, feliway, nothing works. Since the washer broke I have locked her alone in the bathroom to get her to eat, yet she still pees herself. She used to use a litterbox. The interesting thing is that she does not seem afraid of cats or dogs, and lets them snuggle with her.
Meanwhile, her brother is just a normal cat. Just fine. I am worried that the age that we got her at was around the turning point, and it seems clear to me that she cannot be a normal cat. I can't stand that the only way she can live is sitting in one spot next to food and peeing all over her bed. I feel like I'm just barely sustaining her life, but I also don't know how she can be happy. She's too scared of everything that I am positive she'll just die outside.
So I am in need of advice. What would be the best possible solution for this cat? What would you consider if this was your responsibility?
