Sekhmet seems more appropriate, though depicted with a lion's head not a housecat's.
Sekhmet acted as the vengeful manifestation of Ra's power, the Eye of Ra. Sekhmet is said to breathe fire, and the hot winds of the desert were likened to her breath. She is also believed to cause plagues. (Wikipedia)
(Yes! I couldn't remember the name & I wasn't sure anyway, but I knew Bestet was depicted as kitty so in my laziness of not wanting to do one single search I went with the safer choice)
