Don't know what to do.
Perhaps this is premature, but we just don't know what to do. We have had our cat for about 3 years now, ever since she was a kitten. She has always been playful and happy. When we walk by her she rolls on her side and starts purring begging for pets. Always talking to us and wanting attention.
Tonight, around 8pm, she was sitting on the window windowsill and something must have scared her, the window was opened and she went straight through the mesh. She has never been an outside cat. Within a minute she was grabbed and pulled in, all the while she is screaming at the top of her lungs hysterical. On the way up she urinated everywhere. We got her to the bedroom she stays in, but she was very aggressive and actually bit me in rage which has never happened before. All night she would hiss/growl at any noise. Eventually she would let us get close to her and even pet her. We thought it was over, and my fiancee went to sleep in the room. A few hours later (about 1AM) I decide it is time to get to bed. I slowly, walk in the room, watching the cat. She doesn't seem to mind me, half asleep at the feet of my partner. I get in the room and the cat looks curious so I let her sniff my hand and she rubs against it, in the the way she begs for pets. I start petting her and she begins to purr for the first time since the incident earlier. After about 2 minutes, maybe less she bursts out into growls and starts hissing and trying to chase me around. We displayed dominance, the first time in this whole fiasco, and then finally left the room because she wasn't calming down. Now she is all worked up again and is highly aggressive to both of us, so much so that we cannot even enter the hallway to the room she is in without loud screams.
What can we do? She has never behaved in such a way before and we understand she is scared, but we want to make sure she doesn't stay like this...
Edit: I just remembered she has also been far more active in sniffing around, almost like she is looking for something. At least, when she is angry. Not sure if it matters.
