This is hard wired cat behaviour. Big cats do this too. They dig and bury because they are predators and don’t want to leave their wee/poo scent trail.
Domestic cats do this too. Except the parasite in cat’s urine makes rats lose their fear instinct and makes them suicidal..thereby luring them to the waiting hungry cat’s maw.
[..]Researchers have known for a few years that a rat infected with Toxoplasma loses its natural response to cat urine and no longer fears the smell. And they know that the parasite settles in the rat’s amygdala, the part of the brain that processes fear and emotions. Now a new study in the journal PLoS ONE adds another bizarre piece to the tale: When male rats infected with Toxoplasma smell cat urine, they have altered activity in the fear part of the brain as well as increased activity in the part of the brain that is responsible for sexual behavior and normally activates after exposure to a female rat.[..]
