We got two eight week old kittens in August and, apart from the very odd poo by the back or front door, they were excellent at using the litter tray. However the bigger, male kitten started pooing on the kitchen floor a couple of weeks ago and now does all his poos there. Still wees in litter tray. The smaller, female kitten still uses the litter tray for everything. We bought a new litter tray yesterday which we placed in the spot the male usually poos and the male immediately did a wee in it and the female has used it for everything but there was a poo on the floor again this morning. What can we do? My DH, who is not a cat person, is the first one down every morning so he is having to deal with this. We would like them to now poo outside as they have a cat flap but are shut in the kitchen at night. Any advice please?
