There are many articles on ‘dealing’ with cats in the garden. I may just have really good luck, but I have had cats my entire life and have never had problems with them in the garden. In fact, they have been and are wonderful garden companions. They lay in the sun while I work; they prompt welcome breaks with a rub against my ankles looking for a pet; they romp and play fight to entertain. I will comment that an easy solution for misguided digging in the garden is to dump a bag of play sand in an out of the way spot, just for the cats. Otherwise, I bask in the glory of their presence!
