I've figured a possible solution for the cat issue - plant support sticks. You know the long green sticks. Like a roman hill fort.. a parameter of those around the dirt they paw at and a few inside to prevent them just leaping over in habit. The sticks allow the light through, rain but are tough enough for a cat back end to find uncomfortably inconvenient.
I feel that cat and I have come to an agreement, quasi-cease fire.
1. She gets to use the ground under the trees/bushes at the side of the house and if caught short the old fertiliser dump at the darkest spot of the garden.
2. She refrains from dumping or whizzing on the lawn
3. She can sit under the bench for shade, with or without human present.
4. The human is allowed to sit on the bench and is expected to guard garden and cat so dirt rolling, fly chasing, cleaning and general kitten behaviour is allowed.
6. She is allowed to drink from the pond and sit on its walls early morning to catch the sun, or at dusk to maximise the heat stored in the walls. She can sit on the pond windowsill to keep feet warm.
7. She is not allowed under the net of the pond.
8. She is expected to keep birds off the lawn and cats out of the garden.
9. She is expected not to dig up the potted plants.
10. She is allowed to sit in the upturned chair stack (aka 'castle') at any time.
11. She continues to get a treat for breakfast
12. The human is allowed to enjoy time in the garden as long as the cat can say hello and head bump.
13. Any attempt to pet the underside of the cat and the ceasefire is broken and the murder mittens come out.
After Mrs and I gave her a telling off, and stopped her from doing her business on the lawn, I think she got the idea. Especially when I moved her poop and placed it in her favourite spot next to the old fertiliser dump at the back of the bushes.
The scaredy cat plants are pending delivery.. so they'll reinforce it later.
