How old should a rat be to take Revolution?

[ratsr4life]

I have 9wk old babies, both are healthy and happy. I want to dose them with (Kitten) Revolution, just in case their litter mates had them or if there were some lice lurking in the house from my other two. Should I wait till they reach a certain age? Or is it all in the dose amount and age doesnt matter?

I believe they are at an ok age to be dosed but you really should do it by weight.

I read its recommended to wait until they are four months old. But I have dosed baby rescue rats before, with no ill side effects.

Where did you read that?
