The leading US speciality retail chain Pets Mart has lowered its profit expectations for 2005, although it still anticipates comparable store sales growth in the region of 3 to 4 per cent. As a consequence of Hurricanes Katrina and Rita, which cost the company a total of 238 trading days, the third quarter fell slightly short of the forecast sales growth of 2 to 3 per cent. Four Pets Mart stores had to close completely as a result of the hurricanes.
