I last bought several tubes of it 2 years ago or so. I was down to my last one, so I ordered more. It was much cheaper the last time i bought it, maybe the price change happened when the company changed? It seems they were bought out by Merrick? The tube has changed and there is a bit difference in the ingredients. They have added Turmeric, Egg protein and chitosan. Anyone notice a difference in it lately? I haven't used the new stuff yet, it was just delivered 10 minutes ago. I saw the different container and checked the ingredients.
