I have had my chinchilla for a little less than a year. I got her when she was 3 months old. She barely chews on any of her toys or wood. She will chew on very thin twigs (only certain kinds). I have tried different types of wood, sea grass, banana leaves, vines, finger trap shredders (sometimes will chew on these), coconut shell, and pumice stone. She has shelves with different kinds of wood and different kinds of toys. She will chew on something new the day she gets it then barely touches it again. Any ideas about how to help? I have taken her to vet twice (she only has one bottom tooth) to have her teeth trimmed. She has been doing well with grinding them down on her own as we have not been back to the vet in 5 months.
