Hill's Science Plan Feline Perfect Weight Chicken Dry Cat Food

Weight management is one of the most common health concerns for indoor and less active cats. This dry cat food provides the support they need. Hill's Science Plan Perfect Weight is specifically formulated to help adult cats that are slightly overweight or prone to weight gain reach and maintain a healthy body condition - without sacrificing taste or nutritional completeness.

The recipe uses chicken and turkey meal for high-quality protein at 37%, helping to maintain lean muscle mass even as your cat loses excess weight. Prebiotic fibres from dried beet pulp and tomato pomace support healthy digestion, while the controlled fat content of 13% (compared to around 20% in standard adult formulas) helps create a calorie deficit that promotes gradual, healthy weight loss.

This food is also suitable for sterilised cats, who are naturally more prone to weight gain after the procedure. It pairs well with Hill's Science Plan Perfect Weight wet food for cats who enjoy a mixed-feeding routine, and comes in three bag sizes to suit different households.

What sizes are available?

Hill's Science Plan Perfect Weight Chicken dry cat food comes in 1.5kg, 2.5kg, and 7kg bags.

How is this different from the standard adult food?

Perfect Weight has a lower fat content (13% versus around 20%) and higher fibre to help cats feel full on fewer calories. The protein level is actually higher at 37% to help preserve lean muscle during weight loss.

Is this suitable for sterilised cats?

Yes. Sterilised cats are more prone to weight gain, and this formula is an excellent choice for managing their weight after the procedure.

How long before I see weight loss results?

Most cats begin to show visible results within 8 to 10 weeks when fed according to the recommended amounts. Weight loss should be gradual - around 1 to 2% of body weight per week is healthy.

Can I mix this with wet food?

Yes. Hill's Science Plan Perfect Weight wet food pouches are designed to complement this dry food. Adjust the portions of each so the total daily intake meets the feeding recommendations.

Should I consult my vet before switching to this food?

It is always a good idea to speak with your vet before starting a weight management programme. They can help determine your cat's ideal weight and monitor progress.
