If it is the Kirkland Cat Food,that you are talking about,it is a fairly good Cat Food,at an excellent price,I know a Siamese Cat Breeder,and that is the mainstay,of the Diet,that she feeds her Show Cats,and if I could get,to Costco,in Ancaster,I would not hesitate,to buy thatbrand.And mesh screening,or maybe sheets,of privacy latice,,would be good to enclose your balcony,and let you still catch some rays!
