We started giving the cats probiotics a week ago and over the last couple of days they've been more active, especially Gizmo. Giz had been spending more time sleeping than anything else, suddenly he's bouncing around like a kitten again and even Jasper has more energy.
Any idea what was ailing them? Sometimes the four-leggers will suffer in sympathy with their two-legger family members.
Commercial pet food barely has the minimum nutrient/vitamin content and almost no probiotics. It helps keep them from barfing all the time and helps build up their immune systems, something both of them need.
Pet foods/products have become a multi billion dollar business and has produced some inferior, sometime dangerous, products. People spend more on the pooch or kitty than we spent on our kids 30-40 years ago. Thirty years ago Purina was reliable to provide a good quality affordable product--they did the research and marketed good stuff. These days not so much though their premium stuff is probably as good as anybody else's. And according to our local vet--the one who take care of the mini doxie and shih tzu that stay here from time to time--even some of the premium expensive stuff is causing serious problems in cats and dogs, some life threatening. Some pet owners are resorting to making their own homemade pet food, but that is tricky to get the right balance of nutrients. Quality homemade is cheaper than commercial premium pet food though, and takes about two hours a month to make.
If we wind up with any permanent critter residents--we are the designated home for a lot of them out there if anything happens to their owners

--I honestly don't know how I will decide what to feed them. But I'll do the best I can like we all do.
