What the hell does "too old or too dirty for you" mean. I have 24 Gp's that have all been rescued from pet shops and other places, some are young, some are old, some are brain damaged and some did not even make it, so before you trash everyone, think first. I am not a breeder, I am a rescuer who picks up breeders mess, but obviously that does not matter to you, I am not completely blinked in my view, I know the world is full of people that I dont like what they do but I have to try to understand why they do these things, and then leave them alone it is up to them.
There is also no point in giving me any info on dried fruit, as I will continue to give it to my girls they love it, but please bear in mind my pigs all have hard food, hay adlib, alfalfa hay, and lots of fresh veg twice daily
