Okay, so this movie has got to be late 70s to early 80s. It used to be on TV allll the time when I was a kid!

I don't remember much, I think it takes place either on a farm or somewhere suburban (I say farm because I seem to remember lots of plaid flannel shirts on the men). It centers around a family (mom, dad, son, daughter) and suddenly there are a lot of rats around the house. The little girl wants to keep one as a pet (a white one I think). At one point a rat goes down the garbage disposal and the insides are green.

Sorry this is so vauge, I haven't seen it since I was about 6 years old.

The main point is: the big climactic scene involves the little girl in bed and there is the giant salivating rat slowly crawling towards her and up onto the bed. I always used to get too scared and change the channel just at the point when he is leaning over her with teeth bared, and then I'd flip back a few minutes later when everything is okay.

It's been over 20 years! I NEED to know what happens! Please, someone, tell me what movie this is...

Thanks!
