when I use have a bun years ago he got out time after time despite everything we tried, luckly my neighbours knew it was our thumper ( yes very original I know) but me and the kids when younger would be worried sick, he eventually got further down the street and they did'nt know him but i saw a sign in the window saying he had been found, when I went in they had him indoors and very happy being totally spoilt so took the decision to let them keep him (their kids adored him) they kept him inside as he would escape otherwise and he was fine and lived a long happy life, I was just happy for updates on him and think i took a very unselfish decision to let him go knowing the little sod could'nt get out and get killed, I think if the pig is well looked after and tame he has more likely escaped then been dumped, but i dont like to automatically think the worst, hope he finds his owners, the paper ad is a great idea,
