Both of these goddesses are said to have originated from a jungle cat named Mau who defended an ancient tree from an evil serpent (The Veneration and Worship of Cats in Ancient Egypt pg 1).
From this information historians can infer that cats were one of the most respected and cherished animals in Egypt and were worshipped very often.
As stated before cats were very important to the Ancient Egyptians, and were highly respected.
When the people learned that cats ate mice and snakes, they would kill these animals and leave them out to attract the cats to their homes. The Egyptians would protect cats from any outside threats and would feed them. These actions are what lead to the domestication of cats.
Evidence to show that the domestication of cats was started in Egypt is the paintings found from Ancient Egypt, with families and their cats.
We also learned truly how much the people cared about cats when the cats' tombs were found with rats and milk within them. This shows the sentimental connection between the cats and their owners.
