We've had kittens for 8months now, we had them at 1month old. Recently we have had a new neighbour move in, who also has a cat, an older ginger cat. He has taken a liking to bullying my two kittens, comes into our garden and chases them back into the house. What do I do? So far I have tried skirting water in his directio to get him out the garden, but it has a temporary effect and he's back in a matter of minutes. Should I try speaking to my neighbour?
