Query: LitterMaid Cat Privacy Tent - DEFECT -

Littermaid item LM100 arrived in good condition, however, while assembling the Privacy Tent per directions, it was apparent the vinyl cover would not fit the assembled frame without excessive stretching. The two vinyl sections had a 1/4 inch gap between the zipper strips. Calling LitterMaid customer service (NOT)was a waste of time. The service rep refused to acknowledge a possible defect in manufacture and said to return item to AMAZON. Says a lot about their product. Too bad, as the LitterMaid automatic litterbox works very well.
