Susanne - Metacam only has a shelf life of 6 months once opened, so you might want to check your bottle.
Fingers crossed Fifi is feeling better today
I'm sure the date on the bottle is 2013 but that is obv unopened. Maybe I read it wrong. I am assuming that the worst is that it is no longer effective but won't actually do any harm if past exp date but that's why I rang the vet to make sure it would be ok to give. It certainly worked.
bunglycat - has your vet mentioned metacam? I know some people aren't keen on metacam and maybe it's not suitable for Fifi, but when Jaffa has had it for cystitis it has led to an improvement in a couple of hours. Because it's an anti inflammatory and painkiller, it seems to calm down the bladder and stop it sending signals that it needs to be emptied all the time. Jaffa gradually relaxes and settles down once he's had a dose of metacam. The first time he was given it, I was advised to give it once a day (or maybe it was twice, I can't remember now) for a few days and he was also given some anti biotics as a precaution.
