Hi. Baxter is our 8 year old, neutered house cat. He has always used a hooded litter tray (with only one accident ever), and while we have used different types of litter in the past, we do tend to use a very popular brand. The tray is generally the same make too... but about 6 months ago, he started doing a poo as soon as he walks into the tray... and his bum may or may not be sticking out (the flap doesn't close behind him because he hasn't gone in properly)... which means that occasionally the poo is right at the front of the tray or down the front side/on the mat. He mostly still pees "correctly" - ie. he'll go in turn around and pee at the back. This used to be what he did for pooing too, so I'm not sure why he's changed behaviour. The tray is in the bathroom. Our regular tray was always quite big (he's about 5.5kg) but we have been trying an even larger one, but his behaviour hasn't changed. The tray is always emptied on the day and cleaned completely every week, with fresh litter. I have tried cleaning the errant poo with different sprays (bleach, cat deodorising ones) to try and convert his behaviour, but I don't know any other tricks. Any advice? I can't pinpoint an exact trigger for the change in behaviour, but I think he may be associating with bowel issues - he did have some blood in his stools, but the vet gave him an all clear for this and it resolved a while ago.
