I brought home a 6 month old kitty last week to save her from the shelter. At first she was very scared of her surroundings but she came around and has been playing with the toys I bought her. But today, a week after I brought her home, she has slept all day. She hasn't eaten today and she won't play. She isn't running a temperature, or has any visible symptoms of illness aside from lethargy and no appetite. Is she just recovering from the stress of her move, is she just sleeping like kitties do, or should I be more worried. It was just strange to see her go from playful and jumping on the curtains to just sleeping all the time. She is responsive to my love and purrs whenever I pet her.
