SAO PAULO (Reuters) -Brazil's antitrust body Cade approved on Monday, without restrictions, the merger of pet product retailers Cobasi and Petz, a decision on Cade's website showed.

The approval could mark Cade's final green light for the merger, unless an appeal is filed within 15 days. If this happens, the case could be decided by an internal Cade panel.

The cash and share swap deal, which is set to join together Brazil's two largest pet product retailers, was first announced in April last year.
