Actually I am HOPING I have KRV, as all I would need to do is quarantine and I would be able to breed these babies to continue this line. If not, this may be genetic, still looking into this, and I may not be able to. KRV is very easily quarantined out of one's rattery and is only spread through direct contact. It would just mean I couldn't breed for a long time, or place any rats as breeders and go through a few months strict quarantine etc. Anything for my ratties.
