If a disease killed all the mice in a food web how would that effect owls

The owls would have to find an alternate food source and it would be harder for them to survive

Since we are talking food WEB, it wouldn't greatly effect owls because they also can eat other small rodents, or even go after large animals like cats and dogs. I know this because my aunt has 2 owls that go down in the middle of her back yard just to eat animals. They can eat skunks and rats. But if we are really focusing on the question, it would hurt the owls about 20%.

HOPE THIS HELPS YOU!!
