early morning vomiting is classic IBD. Make sure he gets several small meals per day especially late at night before you go to bed. At least 4 meals per day if you can manage it. Unfortunately B12 in a vitamin for ANYONE, pet or human, with intestinal issues has to be given by injection otherwise it just won’t be absorbed. I tried it myself with my Alex and again with my sister’s two cats and it does nothing in pill form when they have GI diseases. It really needs to be injection. Liquid won’t even work, it has to bypass the stomach and go right into the system.

Him being a Siamese makes sense as they tend to get these diseases as part of genetics. It’s very easy to give shots, would you have someone who could help you by holding him? I have instructions and a video on my website: http://www.ibdkitties.net/Shots.html. If not, maybe you could have the vet do it. As far as probiotics I wouldn’t do Fortiflora like the vets offer, that has animal digest which is just gross. I’d do something like Prozyme, which is very good. I’d only do once a day to start with and see how it goes, if he tolerates it well (which he should, that’s a gentle one), do twice daily.
