Both my cats eat the same stuff - mostly nature's menu wet and JWB dry. Milly's poos are delightfully odour free and well formed. Geoffrey's, however, whilst nice and solid and all that, is just unbelievably stinky. I can smell his morning poo as soon as he does it in the morning, it's enough to get even me out of bed to deal with it
How can two similar age (8 ) cats on the same food produce such amazingly different poos?
