Not very tasty!
Although I do not doubt the quality of the food I still wonder whether the daily required amount is enough. On Hills S/D our cat seems to go on hunger strike, as she doesn't like the taste of it! So we cheat by mixing this food with a bit of Royal Canin Sterilised 37 which seems to generate her appetite and provides the necessary daily dose of vitamins. This doesn't seem to have lessened the effect of the Hills food, but she still leaves a lot of Hills in her bowl!
