 Since the late 1990s , both high demand and resulting high prices have fueled increased smuggling of slow lorises to Japan . Although pet shop employees declare that their slow lorises are captive @-@ bred , the advertisements on the pet store websites indicate that their stocks come from Java , Sumatra , or China . New arrivals to the stores are also variable in size and age , which has further led the JWCS to suspect the slow lorises are imported illegally . Official , legal trade of slow lorises prior to CITES Appendix I coverage ( from 1998 to 2006 ) was limited to just ten Sunda slow lorises from Malaysia and Myanmar . A review of 24 surveys covering wildlife trade between 1990 and 2006 demonstrated 228 slow lorises were known to have been traded unofficially each year and had come from Cambodia , Indonesia , Vietnam , and Laos . The major trade hubs were Jakarta , Medan , Singapore and Bangkok . Numerous illegal trade routes for each species were also documented prior to the 2007 CITES vote over Appendix I coverage in the Notification to Parties publication .
