|Keeping Cats out of the Garden
The raking and other soil preparation you do for your plants will also make the spot appealing to cats. They will dig up your seedlings in burying their scat, which also adds an aroma not sought in garden catalogues.
Try these approaches:
If you're desperate, a motion-detecting sprinkler will certainly give the offending feline something to think about. If you're even more desperate you can put down lion dung. If you try this, please let me know how appealing a garden full of lion dung is, with or without cats.
DO NOT USE MOTHBALLS. Mothballs are often recommended, but I cannot condone this practice. Mothballs are generally either naphthlalene or paradichlorobenzene, both of which are potentially toxic, especially naphthalene, which can cause seizures and blood disorders. Keep a sense of perspective: pooping on plants is an affront but it's not a capital offense.
