Just wanted to say we used the baking soda and vinegar method on Sat for two Lg rats and all went very smoothly.

We didn't invest in the Co2 paint ball canister set up yet as we wanted to make sure this was something we could actually go through with and handle before investing to much money into it.

But hubby followed directions from the really good site on line and it all went very smoothly. They both just went to sleep.

So now we plan to invest in the paint ball canister set up soon but will keep the other for back up.

I can say that if done right its a very humane way to go.
But that being said I can also see IF not done right it could turn into a bad experience too.

Anyway just my two cent here.
