We had two experiences with this cat sitter. Both times ended with her cancelling the visit in short notice.
After the initial 'meet & greet' meeting, we set a date for her first pet sitting visit - a paid visit during which I was going to show her the feeding routine. The night before her visit, she called to cancel it because her other client also wanted her to pet sit at the same time. So she decided to cancel our visit. She then wanted to set up the visit the following week.
Then the following week, she called the morning of the visit to cancel it again. This time her excuse was that she had a cold/flu.
I had no problem if she didn't want to take us as a new client. However, she asked to set up the date for her second 'attempted' visit after she cancelled the first visit.
If you are looking for an unreliable pet sitter (and a not very good lier) then Lauren is the one.
