Hello, I have owned cats for over 18 years and I thought I was pretty clued up on behavioural issues but I need some advice please. We have 5 cats, all get on pretty well. Over the last couple of weeks someone has been pooing around the upstairs litter tray not in it. We have recently had a marauding cat that managed to tailgate in through microchipped catflap who terrorised everyone. We also have a cat that likes to sneak up on the others and I wondered if this has made one of the insecure when toileting?
We have recently changed litter from Sainsbury's ultra clumping to Catsan Natural but my hands are tied by the fact our usual litter hasn't been in stock for 6 weeks.
Marauding cat also sits in our garden day in and day out stopping our rather daft lot going out like they used to so there is some pent up energy we are trying to drain by playing.
Any advice gratefully received re litter tray issues or how to get rid of the aggressive cat, we have tried everything and it runs when it sees us but won't be put off.
