Hi again Lara,
Lucy is a pancreatitis kitty too, and I give her B12 injections.
My vet suggested B12, but she did want to test her B12 before starting this treatment.
The initial blood test indicated that her B12 was at the lower end of the "normal" range.
So we decided to go ahead with injections, 0.05ml per week for the first 6 weeks, and then every other week for the next 6 weeks, at which time we tested her again.
The 2nd test result indicated that her B12 was well above the reference range (you can see the result in Lucy's lab&ultrasound link if you are interested), so she is down to 0.05ml once a month.
I haven't tested her since then but I'd like to at some point. Just to see if her dose is right.
This test was rather expensive and required fasting, so I don't like doing it often, but I really should soon.
I think as her 2nd test indicated, you could have TOO MUCH of B12, even though B12 is water-soluble.
I don't know if too much of B12 does anything harmful, though.
I've read someone else mention it on LL before, that she found out that she (not the cat) had too much of B12 in her system, so had to stop B12 supplements.
(Maybe not exactly like this but something along this line, I think it was Ella the Rusty's bean, but I can't remember for sure.)
Since Lucy's dose is soooo tiny, if I buy a bottle of B12, I'd be throwing away probably 80% of it before it expires, so I now buy pre-filled syringe every month.
I just go pick up on the day or the night before I plan to give a B12 shot, so it won't be kept in a syringe for long.
And it costs me whole 50 cents per month. :lol: :lol: :lol:
But to be honest with you, I myself don't really see it doing much for Lucy.
I just continue it in case it's helping, but haven't seen a drastic change I was hoping for.
