Not everyone knows that the Cavyspirit/C&C cage sites exist. If someone uses this sort of cage, isn't it a good idea to send them the link to the site, rather than bad mouth them when they just don't know better? Believe me, there's far worse on ebay than this.
I agree with daftscotslass. Many people just don't know better and it is wrong to badmouth them behind their backs. They think that what they are doing is right because they don't know any better. Maybe you should email him or something and tell him instead of being nasty behind his back.
Its true I got bromers from a petshop and he lived in one of those small cages. The petshop just dont tell you about that kind of things he would still be in a very small cage if it wasnt for this site. People cant find out about this kind off stuff if they dont look around.
