K so im going to start breeding rats. I got two racks that I have built and want to do this the best way. I have seen so many different answers and comments on bedding. I want the best way to keep down the smell (yes I know cleaning is best way). I have seen some people say pine is the best for this but seen alot of people say it is not good to use? So is it ok? what is best kiln pine? pine pellets?Also seen a few people say give them little bit of vanilla extract? how much and does it work? And then I have looked at a watering system at beanfarm.com looks like to do two racks is about $80 is that average price? also is there better place to get a system? sorry just trying to do this right the first time and not have to redo everything down the road.Any other hints on breeding rats would be much appreciated.
