Congrats on the new puppies!
As far as potty training you have to watch them very closely and as soon as you suspect they're about to go, take them to the puppy pads. For Romeo, since he was peeing/pooping under our couch, thats where we put the puppy pads and he started going there on the pads! We thought the pads wouldn't work in the beggining but they worked really well over time. Its too early to take them outside to pee/poop since they don't have all their vaccinations yet, but once they have all their vaccs, its so much easier to take them out every so often. Just remember, you will need a lot of patience and it'll take some time to fully train them. Romeo rarely uses the pads now, as we mostly take him out. But when we leave him at home and leave him in the bedroom, we put the pads down and he's really good about only going on the pads.
As far as the cat, my parents (well dad now, mom passed away recently
) have a cat and she hasn't cared for Romeo from the beggining. So we just let them be, maybe watch them around her when they are young and when they get older yo won't have to watch them as closely....
Hope this helps, can't wait to see pics
