thankyou Saikou,

There is a small part of me which is hoping that it is a urinary problem that can be fixed by pills or even surgery so that we can get it sorted. he has been in England since about November, he has endured a lot of moving around poor little thing but he adapts very well which is good.
unfortunately i cant put the tray on the spot on the carpet as it would be completely in the way.
I've tried to confine him to the living room before but he howls a lot and scratches at the door, although perhaps if i put my other cats in with him he would be ok as he would have company.
I'm going to stock up on some of these sprays as well as putting a couple of extra trays around to try to encourage him and hopefully (im praying) that will do the job.
We took him when he was 2 weeks old and had been badly beaten in the street and nursed him back to health - it was touch and go wether he would make it through the first night but he took well to the bottle feeding so hes still here with us today! I wondered that maybe because he didn't have his mother there to show him how to do things that he may be a bit confused.
He thought he was a dog for a while as he had never seen another cat until he came to England!
I will try that cat litter aswell, anythings worth a go at the moment.
thankyou again
