sorry Salman but you have indicated in previous posts that $$ is an issue for you. Cats are not free. They need to be spayed/neutered, get yearly vaccinations and annual checkups. 1 cat costs about 700 - 1000QAR per year minimum not including food, toys, grooming, etc. How much are you (or more properly, your parents) willing to pay for your pets? If you/they are not prepared to be financially responsible, then don't get any more. It's not fair, ethical or the morally responsible thing to do.
