| | + | implicated, although they now have a larger share |
| | + | of the market than the older warfarin-based and |
| | + | alphachloralose-type rodenticides. Their effects are frequently |
| | + | delayed, and this often results in the late presentation |
| | + | of affected animals to veterinary practices once |
| | + | clinical signs have appeared. The management of such |
| | + | cases is detailed in an earlier article (Mayer 1990), as is |
| | + | that for alphachloralose poisoning (Foster 1995). |
