Gloria,

I know when I purchased interferon and asked the vet she looked 
on the manufacture label and it said 90 days frigerated. I think it 
had if frozen and not defrosted there was not expiration but she felt 
1 year should be the expiration.  The vet had to take it out and 
diluted it 1/2 hour before picking it up. She showed it to me and 
they came in small viles.

Maybe it has to do with the manufacture on the shelf life. Just like 
know there is a debate about vaccinating cats and dogs. If you look 
up vaccines there are articles saying that it is good for 3 years yet 
the vet has you come in yearly.  

There are articles and studies that once the intal vaccines have 
been giving the cat doesn't need vaccines or after 10 years the cat 
has enough immune stored up that vaccines are no longer 
required.

So I think it depends on the manufacture. I know I felt 60 days was 
a safe number to keep refrigerated.

Carla
