Cage Toxic woods not to be used for cages

[HorseLover49]

I am looking to build a wooden guinea pig cage and also a wooden rabbit cage. I was wondering what woods not to use just in case any critters decided to chew on the wood. Right now I am in the designing phase for the cages and needing to know what woods are toxic to guinea pigs and rabbits.

I'd also like to know what woods are bad for guniea's
