Soledad, I have no idea of the noises, but Filou also did some pretty scary ones -sorry for being too plastic but it sounded as if he was strangled. It was his swollen throat.

As there is a bacteria infection in addition to the basical virus the antibiotica should help soon. The idea with the steam sounds helpful.

If he eats it's a good sign.

I keep my fingers crossed and hope it is ok without the X-rays.
