Monte does not have cancer! He does not have a tumor!
We brought him to a specialist on Thursday, and they confirmed it. Poor kitty has gone through two weeks of hell. Blood tests, ultrasounds, x-rays...
The final analysis is that his own body is attacking his red blood cells. No one knows why, but that is why we were seeing blood in his urine, and why he was so sluggish.
He's on steroids now, and some other antibiotics - but we're seeing a whole new Monte now. He's eating again, drinking water, running around, and just so incredibly loving. We can't sit without finding him in our laps almost immediately. And just to hear the most divine music every day (his purr) - there are no words to describe it.
One more visit next Friday to see if he's gained some weight back and to check if the medications are helping his blood production.
Thanks everyone for your thoughts and prayers for my little guy. He may be old (16 next month), but he's got some more time with us.
