Catman -- the reason you didn't get clickrewards for "catfood" purchases is that cats shouldn't eat "catfood" but rather raw meaty bones.
"Catfood" has only been in existence for 40 years, but cats have been surviving for thousands/millions of years eating mice etc. Good diet for cats consists of raw chicken bones (wings, necks) supplemented with raw meat/veggies. "Catfood" contains corn, wheat, etc. which cats shouldn't eat.
(the Netcentives people know this well and therefore do not actually remunerate such purchases...it is a "catfood" conspiracy)
Of as I said to my 9 year old daughter "In our house, I'd rather have cats and bats than rats and gnats."
