Our kitten is being terrorised by a neighbour's cat, which comes round at dusk and stares in the windows. It's black with yellow eyes and looks quite scarey. At first I thought it was a boy cat who wanted to make our teenage girl cat its wife and drink all my beer but another neighbour thinks it's a female. We have an older female cat too, she's been in a few fights with this cat and even got bitten so badly that she got an infection in her leg.
I thought about collecting some of the kitten's urine (easy from her litter tray) and using a lab pipette to sprinkle it around the perimiters of the garden or even sprinkling my own pee around the perimiter. I pee on the lawn most mornings so our cats must be used to my smell. Could this set up a territory, do you reckon?
