UPDATE !

Snoopy was such a brave girl at the clinic! This clinic is a place where new vets are "made" . First, she got examined by 4 students, one of them is graduating in June. They immediately fell in love with Snoopy !! After this examination, they went away to speak with a vet-cardiologist. Then that person came to see Snoopy too. She did the heartecho then . The news is good and not good. Her heart is in a different position than a normal cat, so it was not easy to "see" what the vet wanted to see. Snoopy was very calm and didn't have to be sedated. I was so happy for that!
The vet couldn't see anything else abnormal to the heart; so far so good!
BUT, she was very concerned about something else: she was wondering if Snoopy's diaphragm (midriff) is completely closed. This should be visible n the X-rays pics; but my home-vet forgot to bring those to the clinic in time. She brought them in around noon, but by then the cardiologist was gone...
So, she will phone the clinic tomorrow morning and discuss the problem with the cardiologist. In case there is a tiny hole, even a tiny one, it is extremely dangerous to sedate Snoopy. The sedation would also go through that hole, and she would stop breathing immediately. She would die . So, we know have to decide what to do. If there is no hole, no problem. But if there is, she has to be operated at the clinic, because she will have to be artificially respired during the operation. This makes it a complicated and more risky operation....

I know, this is NOT what we hoped.... . Poor Snoopy....!
I will update with the final results as soon as I know them!

ps. At the end, there were 12 whitecoats and 2 greencoats observing Snoopy. They said she is a vey unique kitten!

Here are a few pics of her at the vet

Before we left:


While we waited for the cardiologist. She checked out the whole place!!
