George was found wandering near the local tube station, he'd been fed on KFC by the local teen brigade for a couple of weeks (having been declared "dumped" by the RSPCA who had been called by one of the kid's parents) before we came across his plight last October.
He was rough coated and clearly had been outdoors for some time, but was a good weight. We took him home, advertised him locally and on the lost pet sites, but no owner ever came forward. Once neutered, he became part of the Tuftyclub almost straight away being very confident and playful and adopted Kuki as his bessie mate.
Now I know that you eat fast and furiously when you're on the streets, but George calmed his eating habits down pretty quickly once he was established here.
However, despite being a very active and boistrous cat, he's gained a huge amount of weight. From his start weight of 4.5kgs at an estimated 12 months last October, I guess he's now nearer 6 - 6.5 kgs and still gaining. His formerly trim waistline has been replaced by a zeppelin shape in 6 months

We have a constant food source available here for my senior kittizens, but that's JBW Senior, lower calorie dry food. He does snack on this through the day and when the wet food is put down twice daily he's never first at the bowls, and isn't all that bothered about stick treats, Dreamies or chikkun either.
I don't want to change the feeding arrangements here too much as I also have three older cats (16+) who like their routines and prefer to graze in shifts rather than brave the free for all at set mealtimes when the younger ones get their Adult food.
All my other cats are within healthy weight ranges, even Sly has dropped to a trim 5kgs since I switched to JWB Senior, but George is just growing and growing!
George will not be collared, we both work full time and the catflap is always set to free access, so I'm stuck with how to find out where he's getting his extra calories from?
Is there perhaps a medical condition that would lead to weight gain? Could it be he's overfeeding here on JBW or is he, as I suspect, looking elsewhere for his calories
