meaning of dreams house

I had a dream where I was in my house (or it was supposed to be my house; it wasn't my actual house I live in) and I had all these pet cats...5 or 6...there were many mice running around on the floor. I said what are all these cats for if the place is overrun by mice? They were sort of chasing them then, one cat was eating a mouse, then i sort of tossed my actual pet cat in real life towards the mice and she started chasing them. My cat was young and strong again, though in reality she is very old and frail.Then I woke up.
