Hiya guys!
Just wanted to give an update on Blaze.
Vet called Tuesday, and said that his blood tests were normal. The x-rays however, seem to indicate Blaze has Irritable Bowel Syndrome. We at least now have a diagnosis about what the problem is.
The vet has suggested that we bring Blaze back for an endoscopy (I think that's how it's spelled) and try new food. Mom is up for the new food, however, Blaze hates the vet, and she thinks he's been there too much in recent times, and that it would only further traumatize him, so we're going to see what managing his diet entails, and how he responds.
We've added an extra litter box on the 2nd floor, and for the past 3 days, and limited his food intake to certain times of the day, instead of leaving food for him to munch on all day.
For the past 3 days, there have been no accidents.
