I'm going to do a bit of research; maybe the local cat charities have some advice. This problem must be happening in other areas.

I'm wondering whether a poster or leaflet campaign would help: explaining what is and is not legal in terms of leaving poisons around, and suggesting ways people can deal with rodents or foxes or whatever they are trying to deal with, without putting poison out. And maybe trying to explain how awful it is for the affected humans when their cat is found dead or disappears. Some people just don't seem to understand how much pets are loved and missed when they go, not to mention the suffering caused to the animals themselves.

Does anyone have any thoughts or suggestions?
