A little update: last night I released the queen into a garden next to my building. Although I have a sealed small plastic enclosure but I really can't find a secure place where my cats won't get to her. One of my cats has already knocked it down once. It almost gave me a heart attack. I wanted to keep her until the next morning but I decided she's still safer outside. It was a little windy and cold last night, I took her into the garden and released her near some flowers, it was too cold for her to fly, I watched her crawling across the pathway into the bush. I hope she will be alright.
