In modern standard Arabic a "cat" is:

قط = cat (qitt)
قطة = female cat (qittah)

In formal original Arabic it is known as:

هر = cat (hirr)
هرة = female cat (hirrah)
هريرة = kitten (hurairah)

A famous companion of the Prophet Muhamed (PBUH) was nicknamed Abu Hurairah (أبو هريرة‎, Father of a Kitten) because he had a cat, and loved raising them.

There're more local names for "cat" in the Arab world i.e in Sudan, Tunisia...etc
