<human>: Here is a goal: To warn against cats and predators staking out bird feeders

How would you accomplish this goal?

OPTIONS:
- Pour sand below the feeder after replenishing it. Cats and other animals will leave foot prints in the sand and you can deter them by raising the height of the feeder.
- Pour sand inside the feeder after replenishing it. Cats and other animals will leave foot prints in the sand and you can deter them by raising the height of the feeder.
