Can a domestic cat withstand temps INSIDE a house if temps reach 22 degrees w/no heat in house?

I'm leaving my house for a few days. My adult cat with about 1 1/2 inches of fluffy hair, food and water will be available and the heat will be off, since I heat my house with wood heat. The temp may drop to as low as 22 - 32 in the house. Will my cat be OK? I have plenty of blankets for her to snuggle into too. I just want to know if she will be fine? Please be truthful....thank you
