Yes,I think that food isn't an issue,the lake is full of roach,rudd and perch,there are quite a few double figure carp(which a 70lb plus cat might have a go at),tench,bream and skimmers,plus lots of pike,mainly jack's 2-8lbs,but to at least upper doubles,the roach population spends most of its time in warmer months up to 8ft down,with the general depths being 10-20ft,around 30ft in two areas,so cats are obviously coming up slowly from below and drawing several roach at once in big gulps,that's without anglers baits,a friend of mine had 4 one night this week including a big forty and a low fifty....
