Hill's Prescription Diet c/d Multicare Urinary Care - Chicken - cat wet food

My three elderly cats get high-quality food to prevent (re-)occurrences of urinary tract issues (one of the well-known "Achilles' heels" in cats) and to ease the strain on their kidneys. All three DEFINITELY do not like this almost sinfully expensive wet food from Hill's. They would rather starve than touch this food. What does this animal behaviour say about this food? Only a cynic would think badly of it...

Unfortunately, as soon as he eats it, he throws it up.
