Thank you everyone
I have come back home , the klitten has survived on tuna covered with layers of fava beans. Beans were used to cover the smell of tuna and still provide some protein
You guys mentioned DRY food. Actually it doesn't take much time here to convert any wet food into dry food. LOL
Of course water is the most important and you seem to have that solved. Are you also providing shade?
The kitten is hiding in a shaded structure, so that is not a problem. Water was placed in a shaded area and has survived too especially it was in a closed 5 liter container. If it was in a pan, it might have evaportated.
We will now look for someone to remove the cat and clean the place.
Thanks again.
