No she will eat it, not sure why, just a puppy I guess. I now have to scan my garden for cat **** each morning before I go an let her out, not really acceptable.
This really shouldn't be an issue, surely cat owners can train their moggies to do their job in the cat litter thing.
I don't know maybe my puppy will grow out of it, but it's not nice to have to deal with this situation.
Try dousing the perimeter of your garden with lemon juice and/or cayenne pepper, also cleaning the areas you find the poop with a cleaning solution to remove their scent markings.
Cats will return to the same place to poop and they will mark it territorially...you need to break that territorial bond the neighbours cat has with your Garden.
Even if the Cat is litter trained it will still do its business outside...you could try a litter tray in a part of your garden, or turning some soil in one part, hopefully the cat will begin to use those areas only and it will be easier to wean the cat away....
