Prescribed by our vet for our rescue cat who was overeating, gaining weight and generally gobbling her biscuits down, she has slimmed down in the last 6 months and is closer to a healthy weight and become more lively as a result. She is now a happy 11 year old moggie and may well become Slimmer of The Year! Cheaper than the vets price and is part of our regular order from VetUK. The biscuits are small, rounded and crunchy and our cat really enjoys them, they have all the nutrients she needs and her general health has improved, her coat is in better condition and she has stopped overeating. We weighed out the recommended dose and found a scoop that holds exactly half the weight of food she needs and then feed her the biscuits twice a day.
