Hello. I've been searching the Internet for a forum to help me! I've got a 15 week old kitten following the death of my beloved 20 year old cat. We've had her for 3 weeks. She's lovely - affectionate, playful, loving - apart from her toileting. We have two litter trays, one covered and one not. I change the litter regularly and use the same litter she had in her old home. She will poo in her tray and wee in there sometimes but not all the time. At night, she pees next to it and we've discovered that she's been peeing behind the sofa during the day. What can I do? Its so odd as she will pee in the tray sometimes. Any help or advice would be gratefully received. Thank you.
