We want to train a rescue cat to come in and out and not poo in the house!
He poos outside - in fact, he has lived completely outside for his whole life, which is one of the reasons we are taking him on - to give him a proper home (agreed with the neighbours that we are adopting him from). But he has already made his way into our house (unbeknownst to us), hidden and then pooped on the floor, a couple of times, despite knowing where the cat flap/exit is. As we officially adopt him, we want him to realise he is free to come and go (I think whenever he's come in, he's thought, 'Well, now I'm in, there's no way I'm leaving!) and want to know the best way to achieve this.
If we initially confine him to one room overnight and get him used to a litter tray that we gradually move outside, plus begin to let him in and out at his convenience during the day, do you think this will be enough to train him to realise this is his home - and not poop on the floors?
Or do we just gradually build things up, letting him in and out, and keeping an eye on him, without a litter tray? It's not a new garden to him - he's already here all the time!
Or is there anything else we could do to aid this transition? Hope this makes sense and thanks in advance for any advice!
