I am too BlueBelle - nothing has stopped them here. Not even the visiting foxes!
They have even climbed into our potted plants on the patio and cra***d in there!
?
Chilli, garlic, citrus smells, sonic noises, water bottles, mirrors, jangly CDs, spikey sticks, special anti-cat powders, gels and so on. Over 20 years we have tried and failed with these and more.
The tiger poo was a non starter as our closest zoo won’t sell poo from their meat-eating animals.
Good luck!
In my opinion, anyone who finds a way to stop them is going to make a fortune!
