It's a good sign that they're trying to hold on. Just keep encouraging them to eat and drink and keep an eye on their bums so they don't get infected. If you need to rinse them off make sure to dry them really well. Blow dryers work great and most of mine actually seem to enjoy them.
unfortunately the weeker one didn't make it,it wouldn't even drink,I tried as much as I could,but I have no explanation as to why this one died but the other is up and about now with more energy
