I was looking in to possibly starting breeding a few feeder rats of my own. I looked into it a bit - picked some color patterns that I liked (I would only be getting two or three adults, so the adults would be largely pets) and read up on breeding.

I mentioned it to an acquaintance, and she mentioned she had two females that she didn't have time for - and volunteered to give them too me, as long as I didn't tell her if I fed them off.

She was the second owner of these two rats, and she found out from the original owner that they had been "vaccinated." The original owner doesn't know what they were vaccinated for, other than that "it was to prevent them from being used as feeder rats." I asked her what she meant - but she just kept repeating that. Even after me telling her that there isn't a "shot" that could keep a snake from killing a rat.

I'm wondering if maybe a regular run of the mill shot like rabies is poisonous to snakes? If I breed a "vaccinated" rat, and feed off the babies - are there any forseeable complications? I'm mainly in this for rat pups - for my two 119g and 130g babies. If the pups are toxic - the babies would be hit the hardest I'm assuming, because they are so small and young.

Sorry for the rambling, but does anybody have any idea, with the limited information I have?

Should I pass over them just in case? (Leaning towards this, or just taking them as pets)
