just out of interest... what breed is your cat? also looking at your cat from above, does he look fat or does he have a nice dip/waist after his ribs? running your fingers under his fur you should be able to feel his ribs with a gentle squeeze...

I just ask as my 18 month boy Indy is a whopping 6.5-6.7 kilos but is *not* fat, just big and well muscled... he's a moggy btw
