Yes, cats as predators can cause great harm, and it seems that both harbors and TNRM colony feeders wholly agree that there are too many feral cats. Both sides do not like to see cat colonies.  The issue is what do we do with those cat colonies.  Cat caretakers opt for neutering and a long-term solution.  Harbors is going for extermination and an immediate solution. Do we trap and euthanize at great cost to taxpayers and the Humane Society? Do we poison and leave bodies to rot, possibly spreading diseases? Do we shoot them, one at a time (because, I’ll tell you, if you shoot one, the rest will scatter and you’ll have to go back…)  I hope the harbormaster is not considering having his friends come over for a shootout party and praise himself for doing the dirty deed for free. Obviously, I would prefer to see managed colonies that don’t reproduce and public education about abandoning cats..
