How can I keep the neighbor's cats from using my raised rose beds as a litter
box? I hear that moth balls work but I have several questions:

1. Does anyone know if this will actually discourage cats?

2. Moth ball is a generic term for three very different compounds: 1,4
dichlorobenzene, camphor, or naphthalene. If the answer to question 1 is yes,
do all three compounds work (as they obviously do for moths) and if not, which
do? Is any one preffered for this use?

3. Does their use in a rose bed adversely effect the roses? If so, can any
soil treatment offset the adverse effects? Are the effects worse than the
ammonia in urine (in relatively large quanity)?

Any other methods to discourage the cats will be appreciated.
