A friend of mine called me today and he is new to Trotlining for cats. He set out some trotlines yesterday late afternoon baited them up and left them alone for around 16 hours, he went to check them out and had 6 nice cats on but they were all dead. I'm not one for trotlining but he was wondering why they were all dead. Did he leave them to long without checking them ?? Someone told him that they all drowned, is this possible ?? I don't set trotlines out and don't know much about it. What is the longest you should go without checking them ? Any help would be appreciated. I'm trying to talk him into joining the BOC so he can get the proper advise on several issues he has but he doesn't know much about computers.
