Rather than have wars about PETA types griefing miners by releasing animals in mining areas, how about something one can eat or use (pig repellent instead of pig bait, or perhaps something one can eat or drink that makes one smell foul to pigs, chickens, butter/batterflies so they avoid you for a while) to have them maintain a distance? I'm getting really tired of avoiding clicking on pigs, chickens, batterflies, butterflies ... but I know that some like them in those areas. So let me buy or grow something that will fend them off!
Or just let me kick pigs and chickens (and give me a net to get the flying creatures!) out of the way :)
