What are the chances that they're pregnant?
Okay, so my husband prefers female rats (I totally don't) and we've lost both of his females recently. So anyway, he fell in love with these two adult female rats, one PEW, and one black irish and brought them home. I must say I more or less approve, they're very sweet and cuddly for girlies.
Here's the problem, the black one has spent the whole week at the store in a big cage with 7 other rats including one adult and one juvenile male. The white one gave birth 6 weeks ago and had not yet been separated from her six week old male off spring. What are the chances that either or both are pregnant? At this point there are no obvious signs. Neither one of them are aggressive. They have been doing a little nesting but no more than my boys do when they're put in a new cage. Neither one of them look just ridiculously fat. But I guess that just could be because it's early. When will they start showing if they are? Should I go ahead and start extra protein in case?
