How do you keep cats away from nests?

Answer 1

It is almost impossible to just keep them away from nests, unless you have full attention on them when they go outside, or keep the cat inside at all times.

There are "cat deterrents" that can help discourage cats from entering a certain area, but most are not 100% cat proof. These deterrents include using predator urine (be careful not to use urine from a predator known to frequent your area as it might be an attractant to that predator), mulch with strong odors that can't don't like (like citrus, cocoa), or ultrasonic devices.

Best choice is to keep the cat confined to a yard or area with cat-proof Fencing.

Answer 2

To keep cats away from nests, you can place physical barriers such as wire mesh or chicken wire around the nesting area to prevent access. You can also try using natural deterrents like citrus peels, coffee grounds, or vinegar around the area to deter cats with strong smells. Additionally, providing alternative nesting sites or shelters for cats can help redirect their attention away from bird nests.
