Please don't give up on them, I have 6 at my house and I can tell you that potty training is tough. If you could use a crate to train them that might help. I have two (2) that will never potty in their crates and one (1) that will wait to go outside, so that leaves three (3) more, and two (2) are the boys who can lift their legs in seconds. I truly understand the pains in potty training, confine them in one area and go from their. If you really have to re-home them,
I will take them. Just give it some more time please...
