hi all, need some advice regarding a neighbours cat that keeps entering our house, has a fight with our cat and pee's all over her stuff while we are out, we have had to lock the cat flap so that he cannot get in while we are out, and only let our cat out when we are in.
we think he has won the fight as our cat, as she only seems interested in hiding and sleeping up stairs which is really unlike her.
we have made loud noises and chase him out of the house when we have seen him walking round like he owns the place, is there anything we can do to get him to realise he is not welcome?....
