Posted August 25, 2007 This is a very useful vitamin when dealing with poorly chinchillas. It can be of assistance when a chinchilla is recovering from an illness and/or has little or no appetite. You can either ask a vet to give your chinchilla a vitamin B12 injection (if you are having to take the chin to the vets anyway). I now use 1ml of Cytacon (from chemists) once a day for a couple of days. No bad side-effects have been noticed by myself - and it does seem to "pep-up" a poorly chinchilla!!
