Hello, I have been breeding rats now for about a year and I have just stumbled across a problem I have yet had to deal with. One of my female rats who has given me a bunch of babies has a giant tumor on her belly I say it's a tumor because I don't know what else it could be. Now here is my question will this effect all the rat babies and the ones she just had is it safe to keep these babies or should I get rid of them unfortunately I put all the baby rats together so about 50 or so are mixed together which would mean a lot of babies dying I just need some advice I like to give my customers the best they can get and I don't want to sell a rat to someone that could kill there snake
