Thank you Claudia and Zip! I sure hope it's not too serious! Thanks for finding that thread. I read through it, so perhaps Marius has something similar? I just hope it doesn't lead into that congestive heart failure. I don't think I could handle losing Marius so soon. I think he's around 7 - 8 years old. It's really hard to say for sure, since he was a "street kitty".

I will update as soon as I find out the results when I get home tonight. All prayers are welcome!
