One of the guys I work with just told me this morning that his grand Daughter has a Guinea Pig that she is putting up for adoption. If you are I can try and get more details, I think he said its name is Lenny so I suspect it is male not female. From what I can gather it has been kept by itself since she got it.
I have warned him about not advertising it for free to avoid it ending up snake food and I am going to pass on the list above to him.
I am going to send him links to this site and a few others so that she can post on them as well.
Was confirmed male, intact, 1.25 to 2 years old (Taken from him mum at 3 months I was told) and not socialized at all from what I can gather as he has been kept by himself since they got him with no other piggy companions.
At least, from what I have been told, they have found him a good home and took some of my warnings seriously.
Sorry to get your hopes up, I was just scared for the little chap when he said they were advertising him on Facebook and wanted to make sure he gets a good home.
I will keep an eye/ear out for any others.
