I bought these after our 12 year-old cat had been diagnosed with kidney failure.
Normally a very fast/greedy eater, he took a long time to finish his portion - never a large one - generally leaving some behind - and still demanding more. So he was not really keen on this thick, pate-type food, and became less and less so.
As far as improving his condition was concerned, however, at his next blood-test this had improved dramatically, being almost normal again, so if your cat likes it, go for it! We changed to the pouches, which he loves and polishes the bowl!
