Because Patricia has always been a free feeder I never thought about how much food she eats every day. Then when I decided to switch her to wet food because the new vet suggested buying cans again, I did a test to see how long it takes to eat one cup of kibbles. It took five days. Now I am wondering if she does not like Blue Buffalo as much as she used to and a food switch should have been made months ago. What is obvious is I will never free feed dry food to any more cats.
