Wildlife driven out of my garden.
I see cats fleetingly in my garden ... I have two Lancashire Heelers!
We have bats, owls, birds (including a song thrush that is driving hubby mad at the moment with its relentless calling and pheasant on the back field), squirrels, a rat under the shed (not sure what to do about that as I want to have a veg plot) and I plan a wildlife pond at some point so frogs 'n stuff are on the agenda.
We've never seen a fox despite setting up a spycam fixed to a tree where we saw the rat and a neighbour's tabby along with muntjacs on the back field. There is also a Rookery in next door but one's trees. So the cat seems like smallfry in the scheme of things (along with my dogs!)
Therefore I have nothing to offer as a cat deterrent other than dogs but dogs do not deter squirrels or rats!
