Yes you'll be fine 😊
Having waged war with my feline friends for years I can confirm that things in ground work very well, where there are bare patches, spaced so they cannot scratch and dig.
Garlic granules work too, but need to be reapplied after heavy rain.
We recently installed an ultrasonic cat scarer and one main moggy who was being particularly insis tent, hasn't been back since.
some work on batteries, others On mains. Harmless to the animal but emit high pitched sound they dislike, as they have sensitive hearing.
Titalky harmless to birds, of which we have many visiting our garden.
