Rat Allergies

Question
I have recently bought a pair of 10 weeks old male Rats, one is Albino the other white with a black head. They are both eating well but the Albino seems to be sneezeing a lot and his nose looks a little red around the edges. I am aware that wood allergies can occour in rats, could this be why he is sneezing and if so what should i use instead of the wood based cat litter i was recomended by my loacal pet store?  

Answer
You could use hempcore/aubeos.  This is a natural product used for horses.  It is dust free and lasts longer.  you can buy it through most horse places.

You can also use wood shavings as wood based cat litter can still carry dust./  DO NOT USE SAWDUST
