Is it enough to feed my cat one sachet of food per day and keep his bowl topped up with biscuits all day?



Its costing me a fortune, he eats 4 or 5 sachets a day easily and the biscuits are so much cheaper than the sachets. Also i only live in a small flat and the cat food stinks!! My cat is about 12 and a boy, he is mainly a house cat, goes out about once a week. Ive started just giving him biscuits through the day and one sachet at night, is this enough?
