I have an 8month old kitty-American siamese. She loves her IAMS kitty dry food. My question is when will she be concidered an adult cat and when do I switch her to adult cat dry food. Once a week I give her milk (whole or 2%) as a treat. Is that okay? I also give her some kitty treats once a week. She is my baby, she always cuddles with me at night time and when I wake up she is there licking my face. Her tounge is very scrapy. Tomorrow she will receive her first shots and she will also be getting spayed.
