My 16 year old chartreux mix recently stopped eating his canned (wet) food.
I've always given him 100-200 grams each day and always had a bowl of dry food ready for him. Recently, he stopped eating the canned food and sticks with the dry food. I tried changing it to like 10 different brands, organic food (very expensive), and self made food. He just licks off the sauce and takes no bites anymore. I am in no worries about his health as he otherwise seems perfectly fine and he still eats (more now) dry food and drinks normally.
Is it maybe just a change in a cat's life? I heard you can buy just the sauce for cats so they can lick it off and get the fats and nutrients they need. Maybe that's an idea?
