Oh I hope they are not pregnant. If they are you will know soon. And contact me asap if they have babies!!! That way I can give you ome advise, hehe. Does should not be bred til the age of four months and it would be sad if they are pregnant. You said they were young still right?

If it is an infection a good round of Amoxi drops or Baytril should do it. However if they are babies DO NOT let your vet prescribe Baytril. It stunts young rats growth.

If the moms have been together a while you can leave together while they have their babies. They will actually care for eachothers babies. If they are young you will need to be prepared to find a surrogate mother just incase the does do not take care of th babies. You should check for milk bellies two hours after they are born. Keeping fingers crossed!!!!!!!!!

Also tetracycline might be a good idea until you can get your rat to a vet. You can give them tablets made for birds in their water bottle. I usually add two tabs for eight ounces of water. If you do this, you need to cover the bottle wth foil as tetracycline is light sensitive. It's also referred to as Ornacycline. It's a broad spectrum antibiotic. You can also buy this at feed stores.
