5 cats at my house-- 3 housemates, adults- 2 female & 1 male, fixed, always lived together. Two new kittens different ages different sexes. Since the kittens came, # 2 female cat wont come in the house for very long , is very aggressive to everyone--hisses, bellos and growls no matter what--growls the whole time she eats ( I feed everyone separately). Cant hardly touch her even though she comes and rubs against me. VERY AGGRESSIVE behavior towards everyone and everything--acts ferel all the sudden. Has become scarey kitty--I am afraid to have her around my family( small children) I cant seem to get her to calm down trying everything I can think of, still I have to put her outside because she is scarey as hell.
