thanks for the advice provided. As mentioned I may have been worrying a little early. She is a delight and has settled very well - even put herself to bed in the kitchen and stayed until 3am
Her toilet habits are a little irregular, however, she will go outside now all the time. It is tricky to guess when she might need to as she is not food oriented at all and nibbles throughout the day. She has James Wellbeloved for her weight put in a bowl in the morning and she snacks all through until about 8pm!
She's tolerating and sort of ignoring the cats which is great. So, now need to beat the seperation issues and travel sickness! Thanks again
