Hi! I am looking at cages to get for my rats when I get them soon. I am getting two males. I was planning to get the single Critter Nation but found out that it does not ship to Australia, where I live. I found a slightly smaller but still suitable cage but the only problem is that the shelves are wire. It is the biggest cage I have been able to find where I live so far. I know that wire floors are not good for rats but is there a way to cover them to make them safe for their feet? I’m hoping there’s a way because other than that problem this cage seems to be the best. Thanks!
