We're looking for 30 UK-based cats who have unfortunately been diagnosed with malignant cancer to take part in our life-changing study.

Over a 10-week period, you'd be testing a brand new food designed to support cats with cancer to see if it can help increase appetite and stop weight loss.

Is at least 1-year-old

Will eat dry food

Is not an outdoor only cat

Is not pregnant or nursing


Willing to provide your cat's medical history
