I would welcome advice from the collective wisdom of the litter tray. I’ve been a cat owner for many years and our current pair (brother and sister) will be 5 in March. We’ve had them since they were kittens and, up to about six weeks ago, they have been very clean - always using the cat flap to go outside. No problems at all. Then DGirlCat did a #2 on the sofa. It turned out she was blocked (unusual in cats, but it happens), the vet expressed her, all fine.
Then DBoyCat thought that the sofa would make an excellent cat toilet and he too did a #2 there. No physical issues. No diarrhoea. I’ve cleaned that thoroughly and now keep the door to that room closed. So, without the sofa option he uses the top of the stairs by our toilet 🤦♀️.
It isn’t every day, and it isn’t urine - he still goes out for that. I now take them both outside to the garden personally. I’ve cleaned the stairs with everything from natural remedies to eco friendly stuff to surgical spirit (I think Amazon think I’m running a small operating theatre). I’ve been hoping to avoid setting up a litter tray for them then gradually moving it into the garden but will do that if you recommend it. I’m at my wit’s end. What can I do to persuade him that the cat toilet is outside.
And this is the handsome young man himself
