Have a very sweet, semi feral barn cat that i've been feeding by my work place for about 2 years. Recently after taking her to vets(found out she was around 4 and 12 lbs) and got her a rabies shot and a shot for flea and allergy dermatitis, brought her home (live in a small apartment by a busy road) and she never wanted to do the safe room thing but gets along with my other 2. Problem is her nightly howling and window door pacing. Im sure its her hunting and nocturnal behavior, shes fine in the day time, even plays occasionally with another semi feral i rescued 2 years ago (have post on her from 2015, she never did this) Will she ever get better and not such strong urges, or do i need to take her back? I have on order the Comfort zone Feliway difusser, to see if that helps. Thank you.
