Had a chat with my vet yesterday. B12 deficiency symptoms are usually lethargy, vomiting and diarrhea, and is often indicative of IBD. She is perplexed that Rafiki is back to eating and has tons of energy. We are going to wait another month and see how things go. If she stops eating or her energy level goes down, we will bring her in for injections. If things are good for a month, we will another blood draw and see what the B12 levels are.
