Welcome to the forum. Unfortunaely I had to take out your link. I cannot tell if your forum talks about breeding or not (we do not allow any breeding or breeder websites to be listed here) but I did find some of the foods and cages pictured on your site as rather poor.
Perhaps you don't know but wire bottom cages are very bad for guinea pig feet. They need to have a cage with a solid bottom and soft bedding.
