Searching nice holiday stay for my cat (Shanghai)

Hello everybody,
I am looking for somebody who can take care of my 16-year old cat named "Vaida" for about 3 weeks (17/09/ Protected content during my holidays. She's very calm (race: British Short Hair), friendly to other pets and people, healthy, castrated, vaccinated, house-trained and uncomplicated.
If anybody of you also has a cat and would like to keep mine for the period mentioned above I would be happy to reciprocate on another occasion.
Alternatively, if anyone knows a nice and calm pet Hotel (for cats) in Shanghai, I would be thankful for any hint.

Best regards and have a nice day,
Katrin Gregor
