Low-calorie cat food or a feeding ball can help fat cats to lose weight, a vet has said.
Joe Inglis, writing for the Metro, was contacted by a reader, Nicola Cunningham, who was concerned that her overweight cat is at risk of diabetes.
She explained that her other cat, who is a normal weight, is not “food-orientated” and the fat cat will steal his food.
Dr Inglis said: "You have to be disciplined when it comes to food and not give in to his demands.
"Try offering a low-calorie food as this should be fine for both cats, provided the other is not underweight, and you could also try using a feeding ball or toy to make them work for their food."
He added that exercise is an important factor in weight loss, so suggested the reader spend more time playing with the fat cat and provide interactive pet toys when the cat is left alone.
It is estimated that around three million cats in the UK are currently overweight.
