My OH would have a hissy fit as he hates cats,the dogs would chase puss out,but one more animal wouldn't make much difference as long as it didn't pee everywhere and it was well behaved,but that's just my opinion,I am sure that if you we're upset and annoyed by puss visiting then it would be very difficult,and we all have a right for our homes not to be invaded by unwelcome visitors,so yes I do think you have the right to be annoyed as it is not something you want,but what to do about it is another matterxxxx
