The city of these cat people was spread between the gaps between different rocky mountains. And some parts of the city were even underground. People of this city lived in caves that they dug in the mountain. The advantage of having the city in between the gap of mountains was that the sunlight was not able to come down in the gaps. Which made these gaps cooler than the environment outside.
The whole city and the roads inside the city were made in such a way that sunlight was not felt anywhere in the city. The city was still hot due to overpopulation but it was comparatively cooler than the desert outside. The shops of the city were usually makeshift shops. The shops were all temporary and were made out of wooden tents.
