Cedar Chips

Cedar is great at masking odors with many animals and also is a great flea repellent. Use these in small animal tanks , in animal bedding or in a run for dogs, which is what they do at Westminster Dog show.
The smell is fresh.

Pros: none

Cons: none

Please do not use these for any animal. Cedar oil is an irritant. It makes my eyes water. I can't imagine what it does to a small animal that can't get away from it.
According to EHOW.com
"Ensure that cedar oil doesn't get into your mouth, eyes or nose when you apply it as an insect repellent, and use caution when applying cedar oil on small children, who may be tempted to taste or lick the aromatic substance. While cedar oil is generally safe to use externally, internal consumption could cause illness."

Pros: None

Cons: Cedar Oil Is Harmful To Humans and Animals Alike
