thrive PremiumPlus Dry Cat Food - Chicken

I’ve been buying Thrive chicken kibble for a very long time and something seems to have changed recently. For several weeks, they were nowhere to be found on any website. When they finally came back in stock, they didn’t look the same at all: - much lighter in colour, - much drier kibble, - a lot less oily than before. Since this change, my cats have been vomiting very badly straight after meals, even though they used to tolerate them just fine.
