You are not being paranoid and better to err on the side of caution. Definitely let other cat owners know because they can then decide what to do, I would hate to not know if it were me and you could prevent a tragedy. Keep your cats in until the menace has passed.
Shame your neighbours can't be arsed to get humane traps... glad they are not my neighbours.
I don't understand this sort of thing, what real harm do mice do anyway? We have lots living in our garage and apart from shredding a few cardboard boxes they do far less harm to the area than the local teenaged population....... and we are not allowed to poison them.
