I have a cat. Thought I'd just start out that way. For more than two years now we have been battling against what has been diagnosed as Diarrhea Predominant IBD. In fact, these symptoms were brought on by an adverse reaction to a combo-vaccine and exacerbated by an "improper" use of an antibiotic injection. Just like humans with IBS, IBS-D, or IBS-C, cats with IBD have extraordinarily low serum levels of hydroxy vitamin D-25, but unlike humans, exposure to the sun will not increase vitamin D levels in cats. The internet is so full of contradictory, conflicting, or flat out inaccurate information on veterinary use of Vitamin D, I thought posing my question here is best.
This is a small cat – 6 pounds (she should be 7) and she is 11 years old. I'm not sure that size matters in this context (a million size matters jokes omitted…). I started her on 2000 iu once per day the first day. Seemed to improve stool frequency, not consistency. I went to 4000 the second day, and 6000 the third day. We are now at approximately 7000 iu once per day which is the same amount that I take personally (a 185 pound male). From experience, I know that with cats being aggressive with dosage is required for most supplements and herbal remedies. Clearly this is improving her condition without adverse effects yet. How high would you suggest I go on dosage? Should I split the daily amount into two or even three administrations (currently by oral syringe in a little broth for ease – she is a cat…)? Frequency of defecation is down to 3X per day but still quite "soupy" with small pieces of formed stool. Are there any other supplements that I should be giving her – she is not getting Vitamin K. She gets multiple strains of probiotic – limited as best we can to the ones that are histamine degrading. She gets a multivitamin (all natural sources) with some enzymes. She gets curcumin. Any guidance you can provide would be greatly appreciated.
