Hi, I currently have two guinea pigs, one I have had for 4 years and one I rescued from a man who just couldn’t take care of him anymore almost a year ago in order to keep my 4 year old company as his cage mate sadly passed away. The piggy I rescued (Charlie) is very brave with new things and loves to run around the garden (we are completely fenced in so there is no danger to them and we let them both just free run around the garden). But I’ve found that Charlie acts very almost bipolar, as in one moment he’ll run up to you and literally stand on your feet and follow you around but then the next, you look at him and he freezes up and just stares at you and won’t move until you actively walk away out of sight from him. He also hates to be approached and hates being handled. The only time he will let me stroke him is when he is at his bowl and eating a food he likes. And then that’s only sometimes, most of the time he runs away and hides as soon as my hand approaches him, no matter how slowly I do it. My other guinea pig however will just sit and let me stroke him practically any time. I thought he might just need to settle in but it’s been almost a year and he still seems incredibly afraid of me, I just don’t know how to gain his trust.
