I just learned we will have to put our 2nd cat down within the last 3 weeks due to FIP. I am in complete shock right now. Back in July we had rescued three adult cats from a shelter where they had spent more than a year. My wife just brought our 3rd cat in a little while ago and we should find out by 4:30 if she has it as well. It is an incurrable disease so the only option is to release them from their misery. I just can't believe this is happening.
