"cats eating commercial dry foods will consume approximately half the
amount of water (in their diet and through drinking), compared with
cats eating canned foods... In older cats that tend to produce urine
with a lower concentration, an increase in water consumption becomes
even more important to avoid dehydration and development of prerenal
azotaemia".

Well, eating dry renal food certainly never hurt my sister's cat; 23 is a
ripe old age and she's still doing fine. If you believe his cat should eat
canned, that's fine, but you didn't suggest a canned renal food to him - you
suggested Wellness or Nature's Recipe. Those were not made for renal disease
and why anyone would suggest them to someone with a cat in possible renal
failure is beyond me.
