I have found a mixture of mince beef and ground snail bait very effextive
for STOPPING visits. Any cat lover can ask for the recipe free.

There were a couple of interesting suggestions for possum deterrents - so
I'm hoping someone has a good deterrent for cats (sans shotgun!)
Recently it seems that all the neighbourhood cats have decided that our
mulch/garden beds are the worlds biggest litter tray. Apart from being
yuck,
they dig up a lot of my smaller plants, and my dogs have a bit too much
fun
playing in the cat poo.... (ewww). Pity they don't keep the cats out of
the
garden.
I've tried citronella based repellants (crystals etc) but haven't found
them
very effective. Any other good suggestions?!
