Our pet sitter, Natalie from Sunderland, fed our elderly sick cat the wrong food, causing him to lose significant weight over a fortnight. She didn't notice that our dog had vomited and peed in her crate, meaning our dog had to sleep in her own vomit and wee for many days on end. She brought flour mites into the house, causing over £100 of damage to our food and meant we had to spend 3 hours cleaning the kitchen when we got home. She got blood on the sheets and didn't even bother to clean it up. She broke both hot taps in the bathroom. She failed to carry out the most basic instructions and lied to us to say she had done something when she hadn't. It was only because we used a petcam that we could check up on her and know for sure she hadn't done what she said she had. She left dirty knickers at the house after she left. She left the bin overflowing in the garden. She left food wrappers under the bed and kebab skewers in the kitchen. All in all, the absolute worst service I have ever experienced in all my life.
