Is how long I've had my boys, but it seems like forever! This time last month they were shut in my spare room hiding behind a shelf, and I'd been soundly growled at by Monty whenever I dared to look in his direction. At times it's seemed like I'd never get much further with him - despite the more gregarious Rolo coming out for strokes and affection the next day, Monty was still happiest when I was ignoring him. He warmed to playtime and gradually started to accept treats from my hand, but still shied away if I ever tried to touch him. He got bolder about sleeping out on windowsills and lounging around liked he owned the place - but for all the seeing Rolo rubbing around my ankles, Monty would just give my offered hand a sniff and back away.
Then when I experimented in letting them outside three weeks in, he seemed to prefer a semi-feral existence in the garden and refused to come back in for 36 hours. At that point I was seriously questioning whether he'd ever consider me as anything but a source of food and provider of toys, but with both cats relegated to being kept in again this past week I intensified my efforts to convince him I'm not horrible. Regular offering of Dreamies as hand-fed treats, keeping up a routine with wet food meals and staying nearby or even holding my hand next to Monty while he's eating, lots of playtime and offering of my hand to sniff. I've also recently tried sitting on the floor and offering chicken as a treat but he has to come and put his front paws up on my leg to reach it.
Well today, four weeks on, we've hit a milestone. I got a proper stroke (and not just a light fur-skim) in while he was playing with a fishing toy. And he didn't completely freak out and break off to back away like he used to. Then - even more amazingly - I got a good twenty seconds of light stroking in while he was eating his evening wet food. He didn't seem overjoyed and purring, but aside from a bit of squirming there wasn't a huge protest either. It may not seem like anything much, but I honestly couldn't stop beaming while it was happening! I hope that this is the start of the thawing of the me-and-Monty relationship and that there's much more where that came from in our future. 
(Just don't tell him & Rolo that in the next couple of weeks we're going to have to make an inaugural trip to the v-e-t-s...)
