Not sure it they're still there, but I think Max has a couple of freeloader carpet snakes(pythons) that have been living in his roof for years.
Many country homes had them as 'guests' if not in the house roof, or under the floorboards, then at least in the sheds and dairies. I'd rather hear a carpet snake scraping across the ceiling than rats cavorting and bouncing about on it. The smell of a shed snake skin thrown up into the roof space was enough to keep rodents out in most cases. Cheaper than rat bait and no bodies to dispose of.
Too many people have a view of snakes as something demonic, they aren't, they're just animals evolved for a particular niche, some are dangerous, some aren't. We don't have to like them but we don't have to go postal every time we see or think about one either.
No one would blink at a cat that lived in the roof to keep rodents down would they? Are cats 'creepy'?
(Well, yes they are really, but you get what I mean.)
An uncle was delighted to see a Blue Tongue one day when he was squatting on his haunches fixing some farm machinery and dropped a screw between his legs, reached down to pick it up and was about to grab about 4 inches of striped tail inches under his valuable bits. He couldn't tell if it was a Blue Tongue or a Tiger snake in the shadows but that silly big flat triangle head finally appeared in the open and he said he was so pleased he grabbed it and gave it a cuddle. Bet the Bluey was wondering about that for a while.
We had a BT in our yard in Sydney for years. We never saw it until just before we left there, but we had seen the midden of snail shells he'd built up and heard his 'clunking' mating calls now and then so we knew he was there. There must have been plenty of others around too as we could hear the 'clunks' getting closer together. Talk about reptile erotica.
We only saw him after a memorable 5 weeks of almost continuous rain in Sydney and he finally gave up and came up to the back porch to dry out. It was huge, well over a foot long, and fat as, so I can't imagine how we never saw him before. But then it was a pretty well vegetated yard by normal standards.
