I have to go on a 30-day trip to Hong Kong and my mom really doesn't want me to take my cat with me even though that can be a possibility. I am thinking of hiring a cat sitter who would come to my place and feed the cat and play with him for 30 minutes. However, how do I know if I can trust that person? She has her own website and stuff and everything looks good but then again I am letting a stranger into my apartment. It seems so risky... I have never hired a petsitter before. Can anyone share their experience with me? Do you pay the petsitter in advance? How can I make sure she wouldn't just take the money and not come at all?
