I bought this to try with my 11 year old cat who appears to have developed sudden allergies overnight to several things including her food. I had read lots of positive reviews on other websites about this food, so I went ahead & bought it. At first my cat tolerated it mixed with wet food, but after a week, she refuses to eat it at all. I'm left with a huge bag (the smallest available is 2.5KG on here) of expensive food that is of no use now opened. I wish companies would sell trial sized small packets of this type of food, esp for cats who are notoriously fussy to avoid a waste of money.
