For the past couple of months I've been trying to remember the name to a horror movie I watched when i was younger. Im guessing its from the 1970's or 80's...it def has a lot of cheese factor to it :p lots of ooze and gooze

From what I remember..

Its about this guy who lives with either his mother or grandmother. The "mother" gets attacked by an animal and has a bite mark that later gets infected. Because of the infection she becomes very rabid and zombie like. The "son" tries to keep it a secret while the "mother" lures people to the house..she turns them to zombies like her by putting infection from her cut in their soup ( i think she attacks them as well).

During all this the "son" locks the victims in the basement so they wont leave the house and attack others...the "son" later cracks up and goes to in the basement to kill the zombies with a lawnmower or chainsaw (something along those lines)

If anyone has any ideas of what it could be pleasseee let me know! I keep thinking its called House on Tombstone Hill but it's not that. The past few days ive been watching a lot of old horror movies and I've been craving to watch it for so long now but i cant find anything about it. My roomate is starting to believe it doesnt even exist :S
