Have a small situation with my 10 month old burmese. There's a guy down the street that has 2 big cats and leaves a downstairs window open for access. My cat jumps in and sneaks upstairs to a cosy sleeping spot. I figured his cats would scare him off but they don't seem to bother eachother. Spoken to the guy a few times and he seems reasonable.. has invited me in to show me where he sleeps and even carries him back around to my frontdoor whenever he finds him. I'm pretty sure he's not encouraging him but I suspect he's there for hours at a time and often comes back with an upset stomach from stealing their cats food. I've suggested spraying him with water as a deterrent but he says he doesn't want to do this. He's getting into the habit of going there multiple times per day and I'm not sure how to stop this behaviour besides keeping him in entirely, which he would absolutely hate. Got a gps collar coming tomorrow to see the full extent of his escapades, but it's not really going to do much besides satisfy my curiosity. Really don't like the feeling of sharing my own cat and especially don't like not being able to control his diet, but not sure what I can do.
