You can also ring or visit the Qatar Veterinary Centre (near Villagio) as they rehome cats and kittens for adoption http://www.qatarvet.name.qa/

Or have a look at the QAWS facebook page, they've recently put up current photos of the kittens and cats they have available. I know they have at least 4 kittens that are under 4 months at the moment.
