Thank You @ruth-girl & @scienceangel!
I was thinking of it, but I am a bit too shy .. However I might do so, because we will need to neuter her in a couple of months (she is too young now - 4 months old) and that would mean an extra 90 Euros to the doctor.
What is so surprising for this kitten is that she was so friendly and sweet...
On the other hand, this could be a chance to take a look at the fundition app and use it for a good cause :)
I am now currently waiting for the doctor's update regarding the operation, lets see...
