Here's one of the chylothorax threads -there are more links in it! All the best for your furkid!

Here Nomilynn and Catsnclay have furkids with chylothorax. Chylothorax means basically that the lymphatic fluid that is usually a thin film around the lungs gets more and more. reasons can be cancer, or heart disease, or nothing at all
It can go away on its own -or stay and be fatal.

But there is hope: it does not mean in all cases that it stays.
