You think you have cat problems, our neighbour has a really old cat which kept coming to our house, and then the neighbour moved away, selfishly leaving the damn thing behind. Now, it always comes in through the cat flap, eats our kitten's food, and meows loudly by the door at 3am. Oh and also, it shits EVERYWHERE. I have never hated something so much, and I do not know what to do, as I have two cats which need to come in and out the house, so removing the cat flap is not an option. I cannot talk to the neighbour about it as she is long gone and refuses to take responsibility for it. And as its really old, I decided to just wait for it to die. That was two years ago, its still alive. I come home from work and its sitting on my bed staring at me, its driving me insane.
