Hmmm...
I absolutely hate it when I plant nepeta, and the cats ignore it...
At my previous garden, I had catnip growing everywhere!
Seems the cats spread it around... When they ate it and then used the garden as a litter box, thus deterring the voles... And planting the catnip...
Y'all plant catnip and then expect to keep the cats away from it?
Cruel dude, that's just cold.
