Hi, Strawbari. I was curious about this, myself. We have 5 indoor cats, ourselves. But, our neighbors' outdoor cats often end up in our yard (outdoor cats won't generally deficate very close to where they live.)
I know the outside neighborhood cats will go into our garden, whenever we have loosened soil. This particularly applies to new gardens. Also, where there is sandy type soil. Their favorite is sand and sandy type soil for a litter box. Could it be that the new garden was all loosened and that was the attaction?
Also, is there a new cat in the neighborhood?
It is true that Marigolds have a negative impact on cat's, physically. I looked up and found this site:

plants (catnip mostly, but other mints also can attract some cats.) The above site mentions
plants that cats like, as well.
