I never dismiss anything anymore until I try it for myself.

A good example is using pine as a substrate for my snakes. I had heard from so many different sources that you can NEVER keep snakes on pine, that I just assumed it to be a fact.... that was until a breeder friend of mine (who has been keeping and breeding snakes for a living longer then I have been alive) told me that it was bullcrap, and that he had been keeping his snakes on pine since the beginning of time without issue.

If you have a bag of cedar shavings I say try it out. Obviously if the rats start having issues, then change to something else. The only one that can tell you for certain what will work for YOU and YOUR rats is YOU!
