Hi,

It sounds like it could be chylothorax. Apparently, Siamese kitties are more prone to these types of diseases, usually from a heart condition. Did your vet tell you what the fluid looked like? Chyle looks like watery skim milk.

Please keep us posted, and if you have any more questions, please do ask. I know that I have had TOO much experience with this disease, along with Catnclay and Ozzlou. Hopefully we can provide you with some insight.
