Thanks very much Saikou, I really appreciate you taking the time to create such a helpful reply. I will take a good look at all the info that you have supplied. Nice to know that my cat could still be around for a while to come yet. I really appreciate the links and information as it is nice to understand more about this and understand what the vet is prescribing. I am not sure what the medication is yet that she is recommending. I will have to find out as I have only discussed the tests over the phone and not in great detail. Thanks again though I will update this thread when I find out exactly what the mediaction is etc, probably is the one you have mentioned though. Thanks again
