My first cat wouldnt pee or the other in his litter tray unless i put a lining of newspaper in it and one just outside it was rather strange but a blessing when i found out. Also i know its not the same but he used to spray my wooden bed posts or the legs So i had him done and invested in a new bed lol The kitten i have now, i brought him home at 9weeks old and he was already litter trained much to my suprise. Do you think maybe he has a fussy request like my first cat did?
