Have convinced dh bella is to stay in till its warmer, he did point out that barney died during a cold spell and this weekend was really cold so possibly someone being thoughtless. bella is back at the vets in just over a week so going to speak to them and see if they have heard/noticed anything as theres only two vets i could imagine anyone around here going to and one is our vets. Am also going to try and make a leaflet and drop that through letterboxes to remind people. Our neighbour is a member of neighbour hood watch and they have big meetings so will try and get her to say something there as well.
