Something fishy is going on here!

So you already know about Flash's (the cat) stomach ailment on Sunday (who by the way I'm starting to have more sympathy for than before.) Then, on Monday, Nina (the cat) started with the same sort of stomach thing. Next, last night when I returned home from work, Dave's struggling with horrible stomach cramps...no vomiting, diarrhea, or fever. Finally (& I use the word finally in a very hopeful way) this morning, around 10, Cait started complaining about her tummy hurting. Again, none of the symptoms listed above. However, finally she couldn't walk standing straight up & when I put her down for her nap, she moaned herself to sleep. :(

So, who will be the next to succumb? And, what is this? Well, whatever it is, it DOES NOT look fun!
