Ok i got rid of the rats i caught and i am still working on the rest. Im not keeping any. But just to play devils advocate.... what about size? There was a HUGE difference btween the ones i caught and the biggest males i used to have in my rat farm(i only dont have any more because i developed allergies).

I really also wanna that k everyone again for the answers. It's been for ever since I had to go on a forum page and you guys have been very awesome and nice.

Thank you
