1. Disorderly Feeding Area
What is the condition of your pet’s water bowl? Is it dirty, or worse, completely dried up? Even if the water bowl has run dry from an accident like your pet knocking it over, an attentive sitter should be checking the water level daily at a minimum, and twice a day if the weather is especially hot.
And don't forget the food bowl. Are there bugs in it? Has dry food gotten wet and left to putrefy, or canned food gone crusty on the plate? A pet sitter who can’t stay on top of the minimal is someone who should be shown the door.
