Webbox's 'kit-e-lix,' which seem to be the feline equivalent of strawberry flavoured Angel delight.
Ingredients include either 2.7% or 3.7% indeterminate protein, about 2-3% 'oil,' a bit of ash, and 88% 'moisture.'
Not even 'water.' 'Moisture.' There was some moist stuff. We put it in.
Does the job, mind.
I have massive doubts about their ingredients, but they make top-end cat crack.
