Question

I fosted a rescue cat that was quite sick with an upper respiratory virus when she got her. We treated her and spoiled her, she had had a bad time and she really acted like a sweetheart. I found a wonderful home for her, she has been there 5 days now, but since arriving at their house, she is clawing furniture like a maniac, howling, and has pottied on their bed once. She simply didn't do those things here. At our house she had a cat buddy at their house she has a dog buddy (and they do play). She is about a year old, has not been spayed and last went into heat on September 12. She did not potty anywhere, but the appropriate places and did howl, but primarily when she was in heat.

question: What would make her potty on their bed? Do females mark their territories? Is it too soon for her to be back in heat? She is scheduled to be spayed next week. Is this just stress? Since she didn't do any of those things here, I'm at a loss as to how to help her new family.


Question: What can be done to calm her down? Why would she be pottying on beds?
