Yes, kitties do bring mystery to your life! My big orange tabby got very sick and went from 18 lbs to 10 lbs in just a couple days. He went up on the roof of my carport, which was a bad sign. I got him down and to the vet, and his kidney function was very low.

The vet gave him some IV fluid, then sent us home with antibiotics. My cat went back up on the carport again, but I could just reach him with food mixed with the medicine. He continued to eat just enough to help him get better.

Today, 3 years later, he's up to 15 lbs and holding. He has been fine, and after about 1 year, his kidney tests were back to normal.

Although I have no idea what really caused it, I know that medicine and patience and love helped. Try to find out all you can, but don't be too surprised if you continue to have only part of the story. Kidney trouble can be bad, but there is hope!
