We got the test results from the urinalysis tonight...and as it turns out Stewie has crystals in his urine. So, I guess that would explain everything we've been going through the past week. I'm not really sure what this means other than we have to go to the vet & pick up special food for him that we'll be feeding him for a month.

Has anyone else had this problem? How serious is it? Also I'm conerned about the special diet since we also have Ollie...the vet said Stewie is not to eat anything but the special food, so that means we'll have to put Ollie's "normal" food away all day. Ollie weighs less than 7 lbs so I'm a little worried about him wasting away...does anyone have any suggestions for how to deal with feeding the cats 2 different foods??
