Bunny Litter

Yes, it does matter what type of litter you use. The chemicals in the litter affect bunny just as certain chemicals affect you.

Litter                                                            What it does 
Softwoods (like pine, or cedar shavings)      Thought to cause liver damage
Cat litter                                                         Zinc poisoning
Swheat Scoop Litter                                      Can cause obesity when eaten
Clay litter                                                       Toxic
Clumping litters                                  Clumping in digestive tract when eaten
Corn Cob Litter                                             Causes lethal blockage
Oat and Alfalfa Based litters                          Good (But don't let bunny eat it!)
Newspapers                                                   Absorbent (Doesn't control oder)
Citrus based litters                                         Work well, but may be hard to get
Paper Pulp                                       Great litters! (Try Carefresh or Today's News)
Compressed Sawdust pellets                          Highly absorbent litter

I use Carefresh litter. It is very absorbent and good on oder control.
I hope this helps!
