It sounds like they mean keep *other* cats out. They say that their cats
*are* indoor.

To the OP, you might try motion detection sprinklers on the perimeter.

You mean that the OP should keep their indoor cats inside the house?
My, your large cerebral cortex must've been working overtime to
generate that polished pearl.

Mary, think with your cortex, type wi' your thumbs, not the reverse.

In The Real World, things don't always go right - and even a careful
person's cats might escape.

The best solution to the OP's problem, of course, would be to fence in
their yard so that their cats have safe access to the outside and so
that other cats cannot get in to said yard.

Failing that, zapping any frolickling felines with water or similar
might dissuade 'em from visiting. Could also try scattering citrus
peels or similar round the perimeter. There are commercial anti-animal
sprays available too (Deer Off and the like), and some do include cats
in their list of victims.

Or you could set up an elaborate, automated missile-defence system
that fires rottweilers at straying cats through a Patented Iraqi
Supergun.
