Well, as no-one else has mentioned it - and it doesn't appear in the FAQ
I looked at either [yes, clearly this is a common problem!]...

I've just [past two months] tried Silent Roar - bought from the local
garden centre - which is, effectively, lion shite. I don't know how they
know, but wee domestic moggies, seemingly, don't like the thought of
bumping into a lion, even under the cover of darkness!

Its worked well in the back garden, but the front will be a good test
too. I only have a couple of relatively small beds within a large
grassed area [shared with next door] out there, and the constant piling
up of the bark mulch that greets me most mornings' means the lions will
soon be let loose.

Now... About these damned moles... Who clearly aren't afraid of the odd,
rogue lion!!! : 7
