3 weeks ago I trapped a feral/stray I had been feeding/providing a heated house for and brought her to vet and then brought her inside my home. She is about 4.5 years old, do not know her previous situation. Anyway, very quickly I felt like I was making great progress, (I had not yet been able to touch her or get too close) but within days she was coming out and eating in my presence, slept across the room from me on an ottoman while I quietly sat reading etc. But then on day 5 I threw some treats towards her on the floor in front of her and she freaked out and ran into her hiding spot. I think she thought I was trying to hurt her Since then she does not want to come out when she anticipates me coming in the room. There were a few times she perhaps didn't hear me coming and stayed on her perch in the cat tree but most times she's back in her hiding spot in a cabinet I keep in the room. I have a baby monitor in the room so I can see when she is out and what she is doing so that is how I know she was "Out" and that she has run into her hiding spot if she hears me coming. It has now been about 10 days since the treat throwing incident and I just don't know what to do. The room is very peaceful, I have soft music playing all the time, I have a feliway diffuser plugged in, I sprinkle catnip in certain places and have tried the Feline Rescue drops in her food. She has a tall cat tree as well as a horizontal cat scratcher, she has 2 beds, an ottoman in front of the window, she has her one super safe dark hiding spot where I know she feels safest (but I can still access her if needed). She does come out after she realizes I probably won't be visiting anymore and she hunts around the room for treats I leave in various spots, she checks everything out and then washes herself on the ottoman in front of the window and then lounges on the cat tree. I try to visit a few times a day and quietly sit and read or talk to her but no more progress is being made. Perhaps I am too anxious about it all? Can she tell that I feel so guilty and sad that I scared her? I would love some suggestions on what to do differently or do I just continue to do what I'm doing? I do have a resident 11 year old female kitty that is very interested in what's going on in the room and who also did see her through the door when I had it open to clean the litter box once. She has not hissed or acted differently at all but wondering if she is scaring the new kitty perhaps? Gypsy, the resident kitty will sometimes scratch the carpet outside the door when I am sitting inside the room and I'm sure Ollie (new kitty) hears that. Anyways would love to hear feedback from those with success in rescuing strays. Thank you!!
