PAMPERS CAT PELLETS MADE OUR CAT VOMIT!!

My cat has eaten your cat pellets for 6 years. Bought 2 of the 2.9kg bags and she has been ill all week - vomiting 7 times in 1 day!! Waiting for response from Martin and Martin complaints division. The bags state them as the contact people. Checked if they were old but expires 2019. Cat refuses to eat them now - changed to Whiskas and she is fine! Will they refund our money, our worry and our crying for our Child? :( will never buy Pampers pellets again!!!
