lizard vs rat

Date: 2/4/2017

I am outside my house. I saw a trash bag. a black spiny lizard around 10 inch long went in the bag and caught a something. it came out of the bag, looks like it swallowed a rat because the tail was hanging outside. Then with one jerk it swallowed completely. It again went inside and caught another huge rat. It came out with the rat in his mouth. He caught the rat with his belly. The lizard tried to swallow the rat head first and loses the grip for split second. the acted fast and bitten the belly of lizard. Lot of weired and disgusting thing came out of his belly...
