Nellie is the one furthest on the right. I am pretty strict about getting her pills into her....still some days she evades me! The weight loss is fairly minimal, but there is a loss of muscle mass I feel, her back bone is prominent and her coat looks scruffy again.I think this was going on even before last check up

Did they just do a T4 test in Dec? If not did the bloodwork show anything outside of range? Apart from a raised T4, the only other thing that springs to mind is she may have some malabsorbtion problems. How are stools? Any vomiting?
Full bloods were taken, I think one slightly raised value so I asked for spec FPL1 which was negative. One of them had been passing very pale stool in the garden, last time I saw her stool this week it looked fine, very stinky, a little pale...so malabsorption does sound an option

Theoretically the heart rate should have decreased now the T4 is in range. Has the commented on this if present on last check?
Present Vet is somewhat cursory in his physical, checks

All this is quite interesting because recently I read somewhere ( think it was Idexx lab report ) where cobalamin ( Vitamin B12 ) and folate has been found to be lower in hyperthyroid cats-I believe even when it's controlled. I know that when B12 is supplemented it aids weight gain. I've noticed this with my IBD cat though diet in his case also helped in combating the malabsorbtion problems which were responsible for his weight loss. Also a specific blood test revealed he had these deficiencies ie cobalamin though folate was raised.

I wonder therefore if you might see a difference after some B12 injections. Do speak to the vet of course about this. At any rate being water soluble any excess is excreted so it won't do any harm. Think you can also buy it online without a prescription-I used methylcobalamin in my case.
I have methyl B12 tablets...I know less effective than injections but will start her on those...can I buy the injections online???

There is a chance also this may be a feature of the long term use of Felimazole-I've only used it preoperatively! Are you a member of the Yahoo group? They might have some more insight into this considering a lot of members there are very experienced in treating the conditon quite often in combination with others as well!

useful one for the cat treatment,..
