Our guinea pig has started having trouble with his teeth. Vet said one had been damaged and so the bottom teeth are growing around it and making sharp spikes. He started making a clicking sound. He's had them filed twice now. Yesterday the vet suggested we could try getting a fruit log to see if this will help. She said to strip the bark, spray with clean n safe and wash. Is there anywhere we can buy these ready done? We don't have any fruit trees at home. Thanks.
