Crazy CL add!!!

personally for the price difference over captive bred....I wouldn't bother.

How do you know if they ate rat poison? Keep them alive for a week. If they ate rat poison, they'll be dead.

Wild rats do seem to be more aggressive than captive bred. I have toyed with the idea so I can add new pure genes for experimental reasons. In the end, it doesn't seem worth the headaches.

Domestic rats have also selectively been bred to produce a lot more young. Good domestic stock should be free of any health problems even through years of breeding within a colony. Introducing a WC would probably ruin that foundation.
