Not sure
I don't know for sure how is this food... I have 3 cats. For one of them is great 6y lost from 5,6kg to 5,2kg in 2 months, the second one gained weight from 7,4kg to 7,7 kg and the third one doesn't like it to much, but still eat a little. She lost from 4,4kg to 3,4kg in 2 months BUT her liver got bad, so bad that she has one week since she doesn't want to eat at all and the blood tests showed us damaged liver - she is 5 y apartment cat and never had health issues. Could it be from this food?
