I adopted a stray cat last year who was living in my alley, got her medical treatment and eventually she came to be a very loving and affectionate cat, albeit a very timid one. I have a strong suspicion someone abused her as she flinches a lot if you move you hand too fast or approach with something in your hand (plus her tail is kinked from being broken). Anyway, she had been improving with leaps and bounds and even liked to join me on the sofa for cuddles and sleep beside me at night. This was a far cry from sleeping under furniture and hiding and hissing, as she was at first. Until this week. I don't know what set it off, but she is terrified of me now. She runs,hides and hisses and won't let me come near.She still interacts with my male cat and is friendly to him, but me, she does not want to be near.I am giving her space so she feels safe and knows she has the freedom to do as she wants. She still eats and used the box (her pee and poop is normal). Should I take her for a checkup?
