We've recently moved house, at the old
House they had free access to outdoors and did their business elsewhere than my own garden. Out of sight and out of mind!
When we moved they used litter trays indoors for 3 weeks with no issues before the cat flap was fitted, there all going out now but we've had a couple of wee incidents indoors (where the litter trays were, easy mistake to make) and they seem to be weeing and pooing in our garden, but the whole thing is slate chips so it doesn't exactly dig over the poo to cover it. We're having to go out with a bag.
I don't know if they're struggling to find their territory from the neighbours cats, can't find any grass areas nearby or what.
I've heard of the tricks, putting citrus and banana peel down but feel it would be a bit of a Dick move if they then start going on my neighbours slabs instead or something. Has anyone got a designated poo area in their garden for their own cats that's worked?
