I have a variety pack of food witj different meats. Chicken, tuna, lamb etc. If i give her chicken one day and tuna the next will that upset her stomach? Its all the same brand, just a variety pack

Im adopting a 3 month old kitty soon and want to know which litter i should get for her? I want low dust or dust free, good clumps and something that controls odor well
