You never know now what you'll be able to get. Most of what I'm buying in the grocery is made in the US, so not in the cargo containers that are waiting to dock. But supply chain issues and lack of truckers is definitely problematic.
We've had to change the breakfast cat food (wet) and will soon have to change the dry as well. Frustrating, as Cooper needs oral care. Science Diet is the only one I can find now, and last time we tried it, he wanted nothing to do with it. One of our past cats had to have teeth cleaned by the vet every couple of years, and it's very expensive as they have to be sedated.
I've come to realize that we've become pretty spoiled in the US - we've been able to get pretty much what we wanted when we wanted it. Having to wait or make substitutions is not something we are used to anymore. It reminds me of when I was much, much younger.
