I have not used it sorry, but hopefully someone will come along soon who has
I do remember reading somewhere about hemp bedding, but cant remember where...... I'll look!
Hemp bedding is a natural product made from the core of hemp plants. Many people use it to bed horses on as hemp bedding is easy to buy in bulk, absorbs urine and water, and reduces odours.
However, when using a hemp product for guinea pigs you must be aware that some brands are treated with essential oils such as citronella (for a fresh smell) and eucalyptus (a decongestant). Guinea pigs do enjoy chewing their bedding, and as Eucalyptus oil in particular is poisonous to guinea pigs, any bedding containing this oil must never be used for bedding guinea pigs on. On the same note, it's not preferable to use bedding treated with citronella oil as this may cause harm to your pets if consumed.
The one hemp bedding product I have found that is safe to use is Aubiose, while products such as Hemcore and Bliss are treated with essential oils and therefore not suitable.
