My 13 y.o. Abyssinian has just been diagnosed with inflammatory bowel disease. In addition to the daily Cerenia and Mirtazapine PRN that she's been on for the past several wks, the vet wants her to begin B12 injections Q 3 wks, a probiotic, and prednisolone. This seems somewhat excessive to me, given that she's done well with the Cerenia and occasional Mirtazapine. It's very difficult administering meds to her, as she is able to detect it in her food. Can you comment?
