 PetMed Express Inc. PETS, 6.44 says its fiscal fourth-quarter sales suffered from a slow start to the flea-and-tick season, but the company expects that part of the business to bounce back as the warm weather sets in. A cooler March in much of the country delayed the start of the flea-and-tick season, a season which normally represents a ramp up in customer demand for us, leading to a slower than expected final month of the quarter, said Matthew Hulett, chief executive of the company, on the late Monday earnings call.
