They get along, mostly. Oy, gotta back up to the beginning, unfortunately.
Joel was the first outside cat. Just showed up one day, I gave him food, he stuck around. Was able to get him into the hallway at first, usually only on cold/rainy days. Then I’d let him inside, he’d eat, sleep, eat, sleep, etc., ’til either I’d boot him out before going to sleep or he’d want out on his own. At one point, he didn’t want to leave, and I didn’t have the heart to boot him out on a rainy night, so he’d often stay ’til morning. No litterbox or anything, so he was smart enough to “hold it in” ’til wanting to go out. He was a regular for about 2yrs.
Coraggio just showed up one day, a bag of bones. I mean emaciated. I’d put out food, he’d nibble a bit, then walk away. Nibble a bit more a while later, and walk away again. Friendly as can be. 2nd day, same thing. 3rd day, screw it, I took him to the vet, had 2 big angry growths in his mouth that already started bleeding, so no wonder why he couldn’t eat. 800bux later (operation, bad teeth pulled, regular bath, flea bath, wadded-up gum removed from between his toes, and a full blood panel), and I got my first healthy ~7yo inside cat. Wasn’t gonna rescue him from the Jaws Of Death only to have him get smooshed by a car, so he was inside for good at that point.
Anyway, he was my first, and took right to indoor life, never tried to make a break for it. Got a gouge taken out from his ear, so he probably ended up at Dr Hackemoff at some point.
Back to Joel, he was always getting into fights with other cats… and losing. At least I hope he was losing, ’cause if he were winning, I’d hate to see how the other cats fared. Got raked on his head, which healed, popped open, healed, popped open, etc., a few times. This last time, he got raked but good, 2 deep gashes in his shoulder which cut “right into the musculature”, and a puncture wound that got infected to where the entire side of his head and neck swelled up like a balloon. Another 750bux later, and he came home all stitched up with a Cone Of Shame to keep him from mischief. But oh, that first night, he pulled that cone off his head, fell off the windowsill, was like a caged wild-animal in a panic at that point. Had to dope him up on anti-anxiety meds (just once, couldn’t keep doing that to him), but still he was trying to claw his way out.
He finally got used to inside life, too, but each one thought of the other as the interloper, so while they didn’t fight, they did hiss at each other constantly. Eventually, they’d chase each other around, but to play, not kill each other. And Joel, always the silent type, started trilling nonstop (looked it up, at you it’s to get your attention, at nothing in particular it’s just that he’s happy).
Oh, Coraggio will still growl and hiss if he’s on the windowsill and Joel wants to climb up there, and sometimes their “playing” gets a bit out of hand, but they do kinda pal around together. Just takes a long time for them to get used to each other.
So yeah, they do play, taking turns chasing each other through the entire house (usually right after I knock off to go to sleep 
), and even play-fight by kinda bitch-slapping each other in slo-mo, unless one/both get edgy and start clawing for real. Just gotta watch them, and chastise them if they’re getting too rough.
